This is a copy of an original post in MHH forum. I copied and shared it again because it’s a great write-up and i bet i will benefit more fromMercedes Star diagnostic SDconnect C4crappy tools.

Thread:SD Connect C4— avoiding garbage

I’m in the market for an SD connect C4mercedes benz diagnostic tool and have been trying to spend my time doing some homework to avoid getting a garbage unit. I certainly can understand what a lot of people have been saying about the widely varying quality that’s out there. I am a EE and PCB designer, so I’m trying to make use of that knowledge to select the best unit that I can.

To that end, I’m going to share what info I’ve collected so far, and when I finally end up buying whatever unit I do, I’m going to do a full teardown on it and post the results here.

As another matter, I’ll openly post details on who I buy the unit from and impressions after receiving it.

Near as I can tell right now, there appear to be about 4 "factories” that make different units.

One thing I’ve been asking all of the sellers for (and I would encourage others to do the same) is photos of the actual unit (including PCBs) with a unique identifier in the photo to prove that the unit they say they are going to send me is the actual one they send me. Of course, some sellers immediately bail at this, but then you know who to avoid ahead of time.

In general, a lot of the components used in a C4 are getting quite long in the tooth. Many of the parts are approaching 20 years of age. Thus, you stand a fair risk of getting pulls (used parts) and/or remarked parts on these.

In following posts, I’ll provide photos of what I can discern as differences between the units along with some commentary about whatever info I can provide at this point.

to, I’ve outlined some things I feel are important to note. They have a set of 4 analog switches on the PCB. In this photo, they are ADG426 from Analog Devices. I’ve seen some clones that use DG526CY from Harris/Intersil. The DG526CY, besides being completely obsolete, has an typical RDSON of 270 ohms vs 80 for the Analog Devices part. It also has a -55dB isolation vs -75dB for the AD part. In short, the AD part is just a much better mux. So with that said, I would insist on any unit I’m interested in using those.

A second thing you’ll notice is the use of can crystals where 4 pin variants were intended. This is just sloppy and cheap. There may also be issue with loading (and ultimately clock stability) depending on whether they matched the loading caps to the substituted crystal or not.

I haven’t had a set of photos high res enough to look at the rest of the actives in detail yet, as most sellers don’t seem to post them.

There’s also an issue pointed out on the bottom of the board where one of the (what appears to be) MOSFETs in (what appears to be a) D2 PAK looks like it was hand soldered. Again, no good.

This next photo is of therelay PCB— I think one of the MHH members posted this from an original SDC4.

.5NU relays and EPCOS S513N chokes. I’ve seen plenty of PCBs where they remove the chokes and stub them out with 0 ohm resistors. That is a high crime in terms of signal integrity. You see a lot of "full chips” comments where these are present, although that is a bit of a misnomer. It should read as "common mode filters present”.

On this PCB, you’ll also notice the use of multilayer ceramic capacitors (MLCC) near the switching supplies. A lot of clones seem to use electrolytic capacitors in place of the bigger MLCCs because of the cost. MLCCs are preferred for switchers because of their low ESR. I really cannot comprehend why the clone makers skimp on these. Even in the US, in reel (e.g. 4K pcs) qty, a 47uF MLCC is about $0.20/ea. That means the difference of probably about $0.50 for the whole PCB. The other advantage of MLCCs is that they more or less last forever, whereas electrolytic caps will eventually dry out and fail (and who knows how old the ones you’re getting are and what the quality is to begin with).

In the upper right hand corner, you’ll see some footprints that weren’t solder pasted during stencil printing. To me, this is a good thing. You know what parts were intended to be populated and which were not. You also get a chance to examine the ENIG finish.

In the next photo, you’ll see theMPC5200 board. This is an 8 layer PCB.

There are a couple of things of note on this board:

(1) The AMD 10/100 ethernet PHY that’s used comes in 2 revisions and a few different temperature ratings. I have to check the details carefully between the rev A and B, but in terms of temp rating, this should be ‘I’ (industrial) vs ‘C’ (commercial).

These PHYs are ancient now, so any price difference should be minimal between the C and I version. Thus, again, I can’t imagine why anyone would try to save $0.01 and use the C version.

(2)(Anturage corrected me here — this header brings out USB, MII (Ethernet MAC), and some other signals)
(Will update below with the location of JTAG when I find it…)

The header at the lower left hand corner of the board is the JTAG header for the MPC5200. For PowerPC, they refer to this interface as BDM. I haven’t seen anyone talking about it on here, but this could be quite useful in some cases if/when the SDC is flaking out. For anyone who’s not familiar with this interface, it allows you to halt/breakpoint/single step the processor. You can also test the memory attached to the CPU etc. Unfortunately, on this particular PCB, some solder paste leaked through (although I’m not exactly sure how this could happen if I think about it…) onto a few of the pads.

(3) The memory chips are at the bottom. They’re DDR SDRAM (I made a mistake when I originally posted this, I wrote that they were not DDR, but upon closer inspection, they are). You can see the series termination resistors between the memory chips and the MPC5200. As others have pointed out, these should be identical and from the same date/lot code. These parts are plentiful and cheap as dirt, so there’s absolutely no excuse for any funny business there.

(4) The Spansion S29GL064N is a 64Mb (8MB) parallel NOR flash. Pretty standard for the time this unit was designed. This is what the MPC5200 boots from and where U-Boot, the RTOS, etc. live. You can dump and rewrite the contents of this flash via JTAG (mentioned above). These parts are still readily available and cheap.

You’ll notice on this PCB that right below the AMD PHY, there’s a 32KHz tuning fork crystal in a 4 pin package. This is the package that should have been used on the other PCB as well.

In general, this particular PCB looks to be of reasonably high quality.

The last photo that I have is of theLCD display.

I’ve seen a lot of different variants of this particular board.

There’s this example ‘FT-C4-LCD’. I’ve seen another ‘LCD V1.1’ variant as well.

The biggest thing with this board is that it’s a HASL (hot air solder level) finish. Granted, this is not the most complex PCB in the world by a long stretch, but it just goes to show you how for these companies will go to save every last penny. Although I haven’t seen the back side of one of the ‘FT-C4-LCD’ variants, the ‘LCD v1.1’ variant seems to use some ST microcontroller. Maybe the FT-C4-LCD has one on the back?

There’s nothing else particularly remarkable about this board, although my impression is that the higher quality units seem to use this FT-C4-LCD variant. If anyone has information to the contrary, I’d certainly appreciate knowing about it.

So as I’ve mentioned before, I’ve been sending these photos to any prospective sellers with SD C4 units and asking them to address the issues I’ve pointed out here in writing.

If they either can’t or won’t, I just simply move on. I’m sure there are some people that will argue that I’m just wasting my time, but that’s fine, it’s my time to waste. I think if enough buyers start insisting on better quality up front, and stop buying garbage, it may encourage the factories to improve their quality in general.

To that end, I’m asking any seller to guarantee, in writing, that I will receive exactly what we agreed upon up front, or that they will have to provide a full refund and pay return shipping. To be fair, I am willing to pay more for that. I’m not asking for a top shelf unit at a rock bottom price.

So for any sellers reading this that are interested, please post a note on here, as it may be of interest to others. No need to PM me. Any experience that I have with any seller, I will report back to on here fairly and accurately. I think anyone deserves a fair chance. At the same time, I will be completely honest and detailed about the entire experience, so please bear that in mind ahead of time. I would encourage others to do the same. I feel like this is one place where open communication will benefit everyone.

To any sellers that might be reading this:

Please understand that none of us want to buy a unit, have problems, and have to deal with sending back to China and playing games with you. All anyone wants is a high quality unit that will work reliably for years. It is better for you and for us to pay a little more up front and get a better quality product. Since you go to great lengths to obscure your production sources, it becomes your job to communicate to them that poor quality is not acceptable.

Here is MB Star DiagnosisXentry/DAS Developer ModeUser Manual,incl three part:

What you need for Xentry/DAS Developer Mode?

When & why you should use Developer Mode?

How to use Developer Mode step by step?

THE MOST IMPORTANT NOTE: you are tryingonyour own risk!!!!!!!!

Be very careful when using the Developer functions! Many of them can cause irreversible damage to the components of the vehicle and may cause personal injury!Please be aware that modification to some specific systems (airbags, braking systems) may make the vehicle unsafe for on road use and may violate the local highway laws, rendering the car not roadworthy in the legal aspect.

This is especially true for the SRS modules, where unintentional usage of developer options may cause deployment of airbags/tensioners and other aggressive restraint systems.

IMPORTANT NOTE: what do you need for Xentry/DAS Developer Mode?

- original Mercedes diagnostic tools like Supermbstar c3or HQ clone like SDconnect C4 china clone mux

-DAS/XENTRYwith good installation

- a laptop running with Windows XP better

IMPORTANT NOTE: why & when should you use Xentry/DAS Developer Mode?

As a presumed DASuseryou have probably learned already that there arenumberof functions that would logically belong to the software options, but they

are missing from the regular DAS installations. These include recoding (variant coding) the control units without SCNs (Software Calibration Numbers), de/activation of commercially sensitive options (in-motion video of tv/dvd), recoding the configuration of airbag units, seat belt reminders, changing the configuration of instrument clusters, restoring damaged EEPROM contents for Comand/APS and other ECUs and many more. There is also an additional benefit: sometimes control units recorda DTCs(error codes) that are filtered out by the production software. Developer kit allowsunfilteredview on the module's error memory, therefore allowingto seeall stored trouble codes, including the masked ones.

The reasons for disabling these functions in the DAS setups seen at the dealership are very simple: firstly, risk associated with using them is too high to open these tools to (very often) under trained and rushing technicians; secondly, there are several legal obligations that put restrictions on what the dealer can do and what he can not - for instance, recoding tv-in-motion, airbagsand emission- relatedsystems fall into this category. Thirdly, electronically damaged components very often result inreplacement,therefore repairing (recoding) would haveadverseeffect on spare parts revenue.

Here is howto :clean ASSYST Plus Memory

Firstly, you need the mentionedDeveloper keymade according to your LAN ID. Before scrapping your old key, take note of the LAN ID (there are some cases when it changes ie. when reconfiguring the hardware) and the current License Key in the DAS.Both informationcan be found in the licensing menu of Star Utilities. Then replace your current key withDeveloperkey, save and restart DAS. After selection of vehicleclassthere should be now a new screen (in German, except V-Series and W221 where it comes in English) informing you about dangers associated with using Developer Kit. You are good to go now.

InDeveloper mode: (tested version 11-2010)

Steuergerate (Control units) ->F3

Aufbau (Body) ->F3

ZGW (CGW) ->F3

Entwicklungen (Development data) ->F3

Steuergerate - Anpassungen (Control unit adaption) ->F3

Programmieren (Update) von Steuergeraten (Control module programming) ->F3

Steuergeratprogrammieren(Auswahl) (Program control unit (Selection)) ->F3

Now we have 2 options to flash the ZGW/CGW with, choose the correct one

Don't panic ! if you choose the wrongfile ,it terminates process and you can do it over again

Confirm Flash pop-up with Ja (Yes)

Afterthatitsays :"Das Steuergeratewurdeerfolgreichprogrammiert"

->"OK" it ask for a reset -> JA (Yes) ->

ECU Reset (FN_ECU_Reset) ->F3 again ->F3

Now you Complete full History wipe

Enable ComandDVD/TV in Motion (W211 W219) and OTHERS

USE THIS TIP WITH CARE AND COMMON SENSE !!! AND OBEY LOCAL LAWS.

In Developer mode :

Audio, Video, Navigation und Telematik ->F3

a screen might pop up with all kind of settings, ignore and press F2

New screen with ESD warning ->F3 COMAND /AUDIO -AUDIO 50oderCOMAND ->F3

Entwicklungsdaten ->F3

Steuergerate-Anpassungen ->F3 Steuergerate-Anpassungen (Variantencoderierung) ->F3

HU Parameter ->F3 scroll down to line: Driving speed is more than 0 kph and

Driving speed is more than 10 kph and BOTH enable them and ->F3 to confirm coding

Now youbeable to watch DVD/TV when car is in motion

Uprate the speed limited in a gasoline (ME-series controller) engine control unit

Log on to DAS, connect to the car, select:

Control Units -> Drive -> ME-SFI 28 -> Development Data.

Then select the Control Unit Adaptations -> Explizite Kodierung

This option works quite the same in Diesel engine models, howeverifound it more difficult to use (quite frequently modules are replying with an error message to the attempt of recoding). I was able to successfully remove the speed limiter on a CDI2 series module from the W210 model and some others as well.

Addrear airbags to the AB control module

Control Units -> Body -> Airbag (AB) -> Development Data -> Control Module Adaptations -> Variant Coding -> Fahrzeugausstatung Kodieren

(the last menu entry can be slightly differentin various module variants)

Select the drop-down list in the field Airbag Hinten Rechts and Airbag Hinten Links – set to YES. Back up to the main Airbag menu, reset the fault codes, cycle ignition, reset fault codes again and cycle the ignition for2ndtime (this step is very important).

Addfoglamps to function as a cornering aid

Select Body, then Driver Side SAM -> Development Data -> Control Unit Adaptations -> Variant Coding -> Abbiegelicht set to ON (" ja”).

Then go to the Passenger SAM (if present, for example in 211/219 model series) and similarly, perform the same coding in the second SAM unit. I have found that quite often cars manufactured prior toyear2003 have the relevant cornering lights option available in the left sam, however right sam is missing it. Not a big problem since these are readily and cheaply available from the second-hand market.

For all the onboard systems to recognize the new function you will also need to recode the CGW or EZS and mark the appropriate factory option in the adaptations.

Hidden error codes

For W211/W219/W230 series with SBC system, go to the Chassis-> Sensotronic Brake Control (SBC) then enter Development Data then call up Fault Codes. Most likely, a car that has been driven for some time will have a code "Event: ABS Bremsung” stored. This Fault/Event is not normally shown in the general menu of DAS – it is being filtered. It actually

doesnot represent an actual error, just a specific condition (hard braking with ABS activation). You will find many modules that actually filter out some more or less useful fault codes.

This menu is also very useful when evaluating vague fault codes (ie: "Hydraulics fault” in the general version in the developer menu can be drilled down to something more meaningful like "rear left release valve stuck in closed state” – this will come in German though).

Adapt ing the SRS control unit to a new car (different configuration, different VIN).

First ofallerase all present error codes in the unit if possible. If there are current faults the airbag module might not get properly reinitialized.

Then proceed to the menu control unit adaptations -> special functions -> Control Unit is released.

From this pointdo not turn the ignition offor reset the control module. Proceed to the menu option "initial startup” where the current configuration will be reinitialized and new VIN can be written to the control unit.

Please pay attention to the specified configuration (ie. Does the car have rear side airbags?) otherwiseyou will end up with a controller that does not recognize airbags installed in the vehicle.

After completing the initial startup, reset the control module (cycle ignition) and erase all fault codes resulting from the startup process.

Extend SBC life

UNDER NO CIRCUMSTANCES USE THIS PROCEDURE MORE THAN ONCE ON ANY CAR AS TRUE SERVICE LIFE OF SBC UNIT IS AROUND 160-180% OF WHAT MB SET THE UNIT AT

Make sure engine is running !!!

In Developer mode you need to go to Entwickelingsdaten - >ansteueringen-> GesamstlisteallerAnsteuerungen

to see how many times brake has been pressed there is a line that says: Bremsenzahler (DJ_GetBrLive)

then 1 line down there you see Bremsenzahleraktualisierenund Lebensdauerzahler F neuberechenen-> clickit !

ParameteruINBR= 0

then click F3

1 line down Bremsenzahler auf beliebigen Wert setzen (DJ_SetNBr) -> click it

Parameter uINBR = 0

then click F3

then scroll down untill you see theline's:

Lebensdauerzahler F neu berechenen (DJ_CalcLiveTime)

Parameter uINBR = 0

then click F3

Lebensdauerzahler F neu berechenen und schreiben (DJ_BuildAndWriteF)

Parameter uINBR = 0

then click F3

Log out of SBC !!

log out of verhicle !!

letenginerun at least 10 minutes or drive at least 10 minutes

If no coils aredamaged ,SBC fault code is not AKTUEL no more

Desactivate seat children and ocuppancy seat in mercedes ml270 cdi

MUST READ !!

Warning !! Warning !!

After completing this procedure

NEVER use a child seat in this seat again

Warning !! Warning !!

EXTREME CAUTION TO BE USED WITH THIS METHOD

In Developermode ,you have to Disable AKZE inpassengerseat.

When you disable this feature, passenger airbag inDashboard,will work ALLWAYS when crash signal come's from the front of thecar ,even if no passenger is sitting in thischair .So in an accident from the front, youallwayshave to buy a new Dashboard + dash airbag as well

Important !!

After you disabled AKZE in SRS unit, youwill notice you can't erase thefault ,or another fault came back (fault coding).

To completeprocedure,you have to unplug the Yellow AKZE connector underpassengerseat, so SRS can't measure anything connected on this input port.

Now you can erase Fault codes inSRS ,and your SRS light inInstrumentclusterwill go off

MUST READ !!

Warning !! Warning !!

After completing this procedure

NEVER use a child seat in this seat again

Warning !! Warning !!

Activate this secret function aslitres, datum, bigger pictures/symbols of some check controls on all models
like W211

AGAIN! DISCLAIMER: The author takesno responsibilityfor any damage caused byuseof theDeveloper Kitof DAS. This option is a very powerful tool but must be used responsibly and withextreme caution. If in doubt, please do not blindly try the menu options – several of them will cause EEPROM or FLASH memory damage, requiring the module to be disassembled and reprogrammed using external tools - this is a troublesome and risky operation. Unintentional actuation of components may cause mechanical failures or even risk of fire - please remember, that inDeveloper Mode DASwill do exactly what you command,all safetychecks and interlocks are bypassed!

Like many others I had a long, long struggle getting myXENTRY-DASsetup working and thought I would share some of the learning to the forum.

There are many non-factory setups available with prices generally ~$600 for aC3 Multiplexer,cables, Dell 630 (built-in RS232 port), already loaded HDD. I didn’t want to spend that much and shoppedon-lineacquiring an external USB HDD with 05-2015 software and VMWare loaded. I acquired the Mux fromNaHaiTech.Apparentlythese Multiplexers are Actia derivatives with the same serial number (6511100299), Part D4. I got the RS232 and OBD cables separately from other vendors as well.

I am using a Dell Inspiron 15 laptop with Windows 10.

VMWaredoesnicely run the XENTRY/DAS software on the virtual desktop through the external USB HDD. A variety of keygens areon-line, or through the forums here to get the necessary keys for WIS/EPC/Xentry. (Just having WIS is a blessing!)

Optimistically I connected it all up to the car (2004 W220.170, S430) but did not get the green "Connected” icon in the desk band. Rats.Howeverthe SDConnect Toolkit showed the Mux as "Part D” but "no connection”. So at least the computer sees the Mux.

I had read all the caveats on the forums aboutRS232cable type, setting COM Port 2, setting low serial bit rate, fake RS232-RS485 modules on the serial cable, and that C3 Part D is unsupported post 09/2014.

I started troubleshooting with the USB RS232 cable and tried one with FTDI and one without. To be certain they were communicating through VMWare I connected each to the serial input of an old IBM w/ serial port and used serial bus comm software to send/receive data from each computer. So I know either cable will work (if sometimes temperamentally). My version of VMWare Workstation (10.0) requires a "Removable Device” (which can be a thumb drive if you want to import data, or the DVD drive, or USB cable) be selected from a "VM” menu drop down.Itsimperative that VMWarerecognizethat you want to disconnect from the host and put a check-mark by the device listing after the dialog comes up asking permission. Likewise when if you switch to the host (ie Win 10 in my case) the device (i.e. USB serial cable) won’t be available unless you disconnect VMWare’s use of it.

So the problem must be in the Mux itself or a cabling issue beyond the serial cable. After much screwing around and getting nowhere I finally contacted the vendor through their AliExpress contact portal. They were quite responsive and helpful. The HDD came with TeamViewer and so one night in the wee hours I setup the system and after several hours (arg!) the Chinese tech operated Teamviewer and evidently changed some Config settings. The green comm light came on the deskband!! Eureka. Short lived. When I restarted VMWare nothing worked again.NaHaisaid it must be a software problem, to purchase a plug-in HDD from them. With so much time invested I decided to get another C3 Mux and RS232 cable, fromMBStarTool.comthis time, the problem must be with one or the other. Shipping was quite fast actually and in a week or so I had the new setup ready. While waiting I investigated the Mux internals for bad solder joints and mapped the pinouts of the serial cable. I’ve worked with RS232 and RS485 in the past and this wiring is non-standard, to my head scratching.

With the newC3 Mux and new RS232 (but theirs comes with a converter box RS232-RS485, and it has internals) I connected it with my VMWare setup and it works! I can operate Xentry and diagnose the problems with my car – and there are several.

I tried the original Mux too and it works fine as well.

Patience pays. The supplier’s directions for setup and operation of this complex system is lacking. And it is, as everyone has commented many times, a very complex set of electronics and software!!! But anyone with an older Benz andlimitedbudget (i.e. why notbuya new Benz if the budget isn’t limited!) will treasure theXENTRY/DAS‘s abilities and save a lot more money in the long run.

Have good success with SD connect c4windows 10.

(Credits to 2007RennTechSL600at http://mhhauto.com/Thread-SDConnect-C4-WiFi-on-Windows-10-SOLVED)

I’m running Win10 on a Dell XPS15 9550 laptop with Intel AC 8260 internal wireless card installed.

After days of investigation and testing, the most important thing to understand is this. The drivers for your wireless card MUST support AdHoc functionality. The drivers are the secret sauce that makes this possible. This can be verified at the DOS command prompt. The command is: netshwlanshow drivers

This command will show "Yes” or "No” on the line for "Hosted Network Support”.

If this line says "No”, AdHoc will not work properly.

Although I’m running Win10, Intel has drivers for the 8260 wireless card for Win8 which will enable proper AdHoc functionally.

The trick is to download the driver first, prior to removing your existing wireless driver. Download the driver ONLY, not any driver file with additional driver management apps included in the downloaded file.

Now you can go into Device Manager and remove your existing wireless card AND check the box that removes all software associated with it. My Win8 driver download file was a.exefile. I double clicked on it and the Win8 driver for my Intel 8260 card was installed. Went to Device Manager, right clicked on my 8260 wireless card and selected Properties. Clicked on Advanced and was able to see several AdHoc related entries. These AdHoc entries were not visible using the Win10 drivers.

AdHoc can now be verified at the DOS command prompt. The command is:

netshwlanshow drivers

This command will show "Yes” on the line for "Hosted Network Support”.

If this line says "No”, AdHoc will not work properly

With AdHoc functionality confirmed, additional DOS commands can now be used to enable Road24h wireless connectivity. The procedures for the additional steps required are well documented in MHHAUTO forum or GOOGLE.

This is what worked for me. Depending on your computer skills, your results may vary.

If you find my posting to be of help to you, Thanks and Rep would be most appreciated.

Happymotoring !

About: Mercedes w220 ESPmodule Variant Coding,esp.for C1511-005 Coding ErrorVariant Coding is incorrect

Model:2002 Mercedes-Benz w220 s55

What is variant coding:

The variant coding in question is set by using factory data. That factory data is basically what chassis that engine control unit is bolted to. Things likeweightof the car, yawsensorand acceleration sensor parameters, moment arms, etc etc.

Once the engine control unit "learns” its variant coding, it is permanently and irrevocably locked down.

* Mercedes Variant Coding requirement:

Star diagnostic tool (better SD connect C4 or C5),ebayormbstartool.com

A specialized laptop, second-hand ok

Working software, original/crack…both ok

(if you’re newbies, better use a diagnostic bundle, avoid lots of issues)

What is C1511-005 Coding Error:

The ESP module reads the variant coding from the ECU. Once read, its” soft” locked.

Your trouble code suggests that the ESP module has a variant coding that differs from that of the ECU.

Is this a recent occurrence? Did you perhaps havean thirdparty ECU tune performed? Was the ESP modulereplaced ?Is the trouble code stored orcurrent ?

How to doW220 ESPVariant Coding correctly:

If you have a STAR diagnostic tool such as SD connect C4, and it sounds like youmay,go to the ESP module under

CONTROL UNITS

CHASSIS

ESP

Fault Codes

Select C1511-005

hit F8

It should show you how many time the car hasbenstarted after the code was detected. "0” means the fault is CURRENT, any number greater than 0 the fault should be STORED and past history. The ( obviously ) higher the number of start cycles the longer ago it was.

(If it was a long ago and a stored code, I would clear it and move on. If it is current, you can force a variant locking reset of the ESP module in STAR diagnostic and see if the code returns. If the trouble code returns, that would make it a current and ongoing error. If that turns out to be the case then perhaps the ESP module has gone "breasts skyward”.)

Read the pre conditions

hit F3

read the sequence and follow it to (hopefully) force a variant codingre-read/write.

It would seem that the ESP reads the ECU on every start up. Having a bad TCU MAY be contributing to the ECU variant coding being off kilter. I would think there would be some P2000-P2564 series codes displayed for that though.

I have no training asa MBmech/tech and offer this as just a possible direction to proceed in. The ( very ) highly paid professionals at the Dollarship or the ( not so ) highly paid folks at a good independent shop should/would have the final say.

Here list reasons why you should buy a Mercedes diagnostic tool with a laptoptogether:SDconnectC5

—With the Dell D630’s dedicated serial port, there was no issue for me…. it was plug and play… I just loaded the HDD from the Seller into my Dell and all I needed to do was activate WIS/EPC andXENTRY/DAS with "activation keys”… I only use the Dell formbstar sd c4purposes…

—Bought an older Dell D630 laptop with a serial port and plan on buying MB SD Star C4 directly installedina Dell D630 hard drive. No Virtual Machine issues.

—Mercedes BenzStar diagnosis C3 / C4 actually specifies the computer or tablet used in the SDS environment… The T30 is rather slow but will get the job done.

—Ifyourever in the market for a faster SDS laptop, the Dell 630 with at least 2Ghz and the speed improvement especially when using Xentry is like night and day.

—the HDD that is pre-loaded with the software for SDConnect 4 by the Seller, is inserted into the DELL D630… The DELL D630 is the fastest laptop with the RS232 feature.

—Need to connect directly intoa RS232port without using an interface – this is why I went for the complete system withlaptop.

—The softwareXentry/ DAS is a bit slow on an old IBM so that it is worth paying a bit extra and getting a Dell D630.

—There is a very specific set of COM ports you must use for it to work. Forexampleyou need DAS to be looking at COMx within the VM session, then VMware needs to redirect that to COMx which is a ‘physical’ serial port on your machine.

—It’s probably because it has a real com port. Most laptops these days have just a USB port and things don’t always work right if you’re using a USB toRS-232converter. You wouldn’t want to brick a component during an update if you’re using USB. The other option would be to get a C4 system, but then they cost more. I think there are a couple other systems out there like IBM that also have real com ports.

—The PART D mux(C3) is a serial ported mux—that’s the reason for the Dell and IBM older laptops.

—The PART Wmux(SD connect C4) is and Ethernet/wifi connected system and that is the reason for use on other laptops—the issue is the operating system currently DAS Xentry only runs on XP.

—Plug and play!! It is more convenient for users because the software forC3/SDC4 diagnostic tool will be pre-installed before delivery.

Here are MB STAR diagnostic kits (tool+laptop)for sale:

all software pre-installed!!!

ready for use!!!

MB SD C4 overcomes the shortage of C3, C4.

—covers a wide range of vehicles including trucks and some cars that C3 and C4 do not support;

—supportswireless diagnose;

—not only supportK linediagnose and CAN BUS, but also UDS diagnose protocol. Because old MB STAR C4 main board do not have UDS chip, so old MB STAR C4 can not support it;

—now use Lan cable to connect, can fit all computers(not only IBM T30);

—adoptsMilitary quick swap technology,andsupports10,000 times pullplug, more stable;

ClonedBENZ SD C5 ConnectAdvantages:

—efficient diagnostic program and complete vehicle database;

—advanced upgraded VCI+ communication interface;

—support Wired/ wir eless connection.

—Besides the software c3 and c4 own,it added three more software: SD Media,Xentryand Smart TAN Code.

SD Media: Video and PDF lessons;

Xentry: New software releasedXentrysoftware for diagnosing W 204,W207 and W212 which C3 and C4 does not support;

Smart TAN Code: Opened special function in DAS program with Smart cars 405/ 451/452/ 454.Besides, it also opened more special functions, such as engineer mode, remove limitations,etc, which Star C3 and Star C4 do not have.

I hadXENTRY DASinstalled and no help linkwereworking from DAS, it was going to some URL every time I clicked onhelpbutton, so I decided to install WIS/ASRA asstandaloneoption onsamelaptop.

This is how to get WIS/ASRA to link bothXENTRY&DAStogether so I can get help working fromXENTRY/DAS.

You justneedconfigure yourWISmode:

Open SDNC at your taskbar

>>Click tab Configuration

>>click Yes

>> click Tab Server

>> Click Wis offline

>> then Press OK

ThenXentryand DAS will be linked with the WIS program

I use C4 with Xentry works good for me.

Firstyou must buy cd connect c4 or c5 if you want coding and programmingMercedes Benz

And you also needother toolwhich can renewusdcontrol modules

LikeavdiSimon tech Mercedes instrument programmer vvd2

I usexentry09.2016 works great, you can find premadeacronisimages and installation version here, just search for Xentry.

It’s good fortrouble shootingand coding.

In somecasesonlinescncoding requiresa MBserver connection.

You find members here that offerscncoding via team viewer.

Vediamo is also available I have not used it a lot but it lets you code and program on a deeper level.

I got my c4 fromhttp://www.mbstartool.com/not sure if there is a better source.

Both sd connect c4 and c5 work good in coding and programmingMercedes Benz

but as forchinaclones,iprefer sd connect c4, c5 just in c4 casing

MB SD Connect C5vs. SD Connect C4: The software of SD Connect c5 is the same as that of SDconnect c4, but the hardware of SD C5 is better and stable than SD C4:

1. The host communication connection end USES from design, to avoid inadvertently fall in the normal use of the communication port to connect and communication failure, etc.

2. DC 12 v power supply design/host upgrades to avoid the battery installation/battery voltage instability/host can’t enter the shutdown state, etc, caused by the motherboard and rapid aging of the battery.

3. The host CPU radiator surface and perfectly fit alloy shell, good heat dissipation effect. Equipment running smoothly, don’t crash.

4. The host USES the tamper clasp,should toavoid fragile warranty sticker damage caused by the warranty disputes.

5. Host wi-fi protected the upgrade for PC plastic shell, solid quality does not affect the wi-fi signal.

6. OBD main telecommunication lines connected to the host end upgraded to VGA15 industrial-grade connector.

7. Network upgrade for gigabit connections/pure copper wire core/double layer aluminum foil/woven mesh/silica insulation material. Gigabit communication Against interference/pulling open circuit / / fracture in low temperature.

This is how to connectSD Connect C4with Xentry 2014, that failed to registrer my multiplexer and hasn’t LAN connecting into a SD connect.

Solution... here you go.

You should connect " Wired LAN " MUX to your PC.

Then switch a your PC's icon " wired " .

Changed --> to next ( uploaded configuration movie ) pass : our major pw.

Not changed --> check you wired LAN driver and cable.

Many troubles had SD connect wired LAN module.

If OK your PC and cable

sdconnect_config000:

https://mega.nz/#!bo92ySQB!ajjQoIrVWXS4TmNO5PnDFF31gY7EQFRlC-hSz0RpK_wIf it doesn’t work, try to reinstall " SD net control "

Good luck.

After ICM, you will see Control Unit Adaptions :

From there, select Special Equipment

• Then go to the drop down tab and change it from PRESENT to NOT PRESENT, and click F3.
• After that, turn off the car, with the doors closed.
• Wait 1-2 mins and start the car back up (no more ABC codes and no white or red lights).

Here is the issue and solution of how to get Xdos Xentry 17.3.5 to work fine on Mercedes C 205 when users but tried to access C 205 it says "files missing”.

That is, update C4 and it will work!!!

To updateSD connect C4interface, make sure you have 6xAA 1700 mAH rechargeable batteries inside which are already fully charged.

If no batteries or weak batteries, often parts of the update will fail.

If you put in non rechargeable, then there is risk of explosion!

Caution: 6xAA rechargeable batteries!!!!!!!!!

This is a W221 tutorial created for W221 owners with diesel engines.

How to change the heater booster system to a fully functional auxiliary heating system.

 

Tools & Stuff you need:

The Mercedes S-Classes (W221) with the diesel engines S320 CDI & S400 CDI are equipped as standard with an heater booster system. The heater booster switches itself on from an outside temperature of approx. 8 degrees independently and warms the cooling water, so that the engine comes faster to operating temperature. There are two types of heater booster systems: electrically operated and fuel operated. On the W221, fuel-powered heater booster were installed. These heater boosters are fully functional auxiliary heating systems from Webasto, which are only restricted in your control.

In the following course I describe what you can see, whether you have an heater booster system and what you have to convert, so that the booster can be used as a real auxiliary heater.

Standard climate switch (upper panel) without heater booster:

Cars with this switch can only use residual heat after a ride….

Climate switch (upper panel) with heater booster:

Only diesel vehicles have this switch… Heater booster turns automatically on an off, depends from the outside temperature…. You can also turn it on manually…

Climate switch (upper panel) with auxiliary heating:

This ist he switch you need to control your auxiliary heating system… Red LED turns on if the system is running… And the other LED turns yellow if you programmed a departure time…

Start the modification:

Use the wedge and fold away the two covers….

…next step turn out the two Torx screws…

….after this leap out the grid to find tha last Torx screw….

….if you have all three screws turned out, leap out the wooden modling….

As can be seen in the pictures, now disconnect both plug connections and loosen the four screws. Then simply insert the new control unit. Installation in reverse order.

Once again everything is put together, now it goes tocodingviaSD connect C4…

You have to code these three ECU:

You can choose two ways for coding:

choose ecu central gateway….

…. Now follow the red arrows….

… now change the equipment „auxiliary heating" on available….

….. now switch tot he upper control panel and follow the red arrows….

… change the option auxiliary heating (Standheizung) to available…

… the last step ist o change the settings in ecu head unit (comand)….

…. go to adjust ecu….

… select the section „MMI controls" ….

… last step, set the „Independend Car Heating Installed" option to YES…

Now all necessary steps have been completed and you have a full-fledged auxiliary heating system. Before using, turn the ignition off and then on again.

If you now open the climate menu in the head unit, you will find a new menu item: "auxiliary heating departure time” Here you can pre-program up to three departure times. Depending on the outside temperature, the system will heat up the car for up to 50 minutes.

… new menu looks like this…..

Hints

Much success in conversion!

Some important tips of Mercedes BenzW212 7G M Mode VariantCodingusingVediamo.

Purpose:

W212 7G M Mode Variant Coding

You need:

Vediamorunning withSd connect C4

SCN coding database

Variant code:

Y2KY

The important tip-

Credits to BetaMar & StarRacer in http://mhhauto.com/Thread-W212-7G-M-Mode-Variantcoding-with-Vediamo?page=3

BetaMar

I want to have M-mode in W212 E500 4matic 2010 model 212.090 SA801 – YOM 10/1, at the moment my variant code is Y2KX, does anyone help me to know the right code for M-mode ?

StarRacer

That’s interesting. I’ve got nearly the same car (W212 from 2009) and I’m also looking for the manual mode. My variant code is Y2KY.

Someone recommended to try three codings before and after the current one but I’m a bit hesitant with this.

The coding contains several properties of the car including 4Matic or RWD. In contrast to the RWD ones, the 4Matic have a torque limitation to protect the gearbox etc. when starting with full throttle. Therefore, a genuine 4Matic variant code would be preferable.

I think in the 7G coding collection there was no W212 E500 with M-mode. The next "match” could be an S500 4Matic (221.086). From the thread mentioned its variant code is YE25. Not sure if this one has M-mode, though.

BetaMar

I want to confirm that in 212.090 with MY2010 SA801 M-mode work very well

with Y2KZImidietly after coding there was error showed in KI display "presafe function is unavaiable” but after ignition off/on everything works!

For 212.090 MY2009 SA800 correct coding is Y2AR

StarRacer

SUCCESS! Now with working M-mode! Y2KZ also works for me.Same error as above after first start which went away with the 2nd start.

Test drive was successful. One drawback, however: The gear switching times in M are not better than in C or S. Some years ago, I read from an S211 (E500 M273 with 7g) which was given M-mode and the owner claimed significantly faster gear switching. He did it the official way: Changing VeDoc and online SCN coding. Maybe there’s more to it than just the VGS variant coding.

Good luck
