MB Star Mercedes SAM Coding Guide

 Mercedes Benz W220 has 3 SAMs, Rear, Front Left and Front Right, and on this case there is only a couple of Alarm Codings in the Front Left SAM, so the pictorial shows you how to reach the codings. Here we show you how to select a Coding to get it’s other options and then you all done fiddling which Icon or (F5 button) you hit to actually carry out the coding otherwise it will stay as it was before after you exit the Coding screen !!

 

Note that if you do screw it up, and weird stuff happens, you can go back in and alter Codings again, so panic ye not !! What you do here is not irreversible. What I advise is to screenshot and save the Codings that are in the Module before fiddling, so you can go back to base line if necessary 

Follow the pictures, note where to click by where the cursor arrow is, which takes you to the next screen, and all MB Star SD C4 diagnostic users should know by now that if you wanna go back a screen click F1 or the /\ Icon .

So here we are, inside the infamous W220.

Select your vehicle screens

That will get you to the next Control Units screen which should also be familiar.

So Highlight Control Units and click F3

Now you need a bit of knowledge or have to go looking in systems (Drive / Chassis / Body etc etc), I happen to know SAM’s are Body, highlight and hit F3 .

Lets look at Front Left on this vehicle, highlight Control Unit Adaptations and hit F3

Now you see Read Coding And Change If Necessary, yeah yeah, Highlight and F3

There is only 2 Alarm Codings to see in this W220, the SL R230 and others should / might have more model specifics, so now we gonna use the same procedures as above and show you a whole bunch you can meddle with in ICM (Instrument Cluster) so go back to Body Chassis etc and ICM is not in “Body”, (3 pics back !!  keep the heck up !! ) it is actually found in “Information and Communication” (of course it is) 

Now see I’ve magically jumped into the ICM by going back a few screens and re-selecting to get to ICM

Highlight “Control Unit adaptations” and “Variant Coding” and hit F3

Now we can really mess things up, seriously though this shows a load of version codings lets look at which is the drivers side, pretend this screen says left….

So highlight Left, click F3 it will take you to the options, so we wanna change it to Right, now, after highlighting Right click F5 in this screen and that’s that job done come out of ICM then go back in and re -read it just to make sure it is stuck !!

This next screen shows you another list of stuff in the W220 Cluster to play with

There we go, how hard was that.

Now, just take note every Car model is different, so for example there will be less or more codings depending exactly which car you are working on.

Earlier Platform Cars like R170 will use DAS for Motor Codings, (note there is a special procedure needed as the ME has to be unlocked), unlike a SAM, ICM etc which don’t need un-locked. There are other modules such as ICM on R170 that you have to access it’s Codings via the HHT Menus, that is kinda self explanatory.

Next upwards platform Cars like W220 are all DAS program Codings.

Mercedes VGS2 Virgin Modified CBF Download

 The CBF file will help people who have no tools to virgin 7G-tronic VGS2 unit.  If you changed the TCU VGS2 control unit, you can use this vgs2 virgin solution using vediamo.

 

 

Years ago I found a bug in 722.9 software, which allows to virginise the VGS2 units without need to calculate “sonderhash” or anything else. It is a reference to diagnostic procedures that are not implemented in the CBF files, but exist in the TCU code. So it is possible to call a normally inactive functions which remove personalization, activation and set transport protection on. To make it easy to use I modified original CBF so that this function can be performed just with one mouseclick.  I use it till now mainly to exchange broken VGS2 with used but good ones.

This solution affects all 2nd generation units (VGS2) with part number A 0335457332. Unfortunately, this “feature” does not work on VGS3 units because their EEPROM memory is double sized and TCU code cannot properly execute internal procedures. So it will not work on 3rd generation units with part number A 0034460310. However, in many cases and cars produced even after year 2008, which was factory equipped with VGS3 you can still use VGS2 as replacement.

To connect with TCU you need to have also normal VGSNAG2.cbf file. So if you have already Vediamo (no matter which version and which MB Star MUX) you just need to replace your vgsnag2.cbf file with modified one and you will be able to bring your VGS2 units in virgin state. After that, to make them than fittable to any 722.9 gearbox, you should flash them with correct software, set right SCN coding and relearn range sensor. All this is possible using Vediamo offline.

This will work on any vgs2 conductor plate. Erasing of personalisation and activation on 7G-Tronic TCU with part number A 033 545 73 32 by Vediamo only. No need to calculate hash or security access.

Using this VGSmod2.cbf file you must be also able to establish communication with TCU by pressing F3 button. It you have no connection – check cables, CAN resistor or interface (MUX).

After you are connected, press F6 button on your keyboard – it should read DTC faults. Than you can press the button safe data.
Do the same with with F7 button.
