W220 ESP Variant Codingwith SD connect C4

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 like weight of the car, yaw sensor and 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), ebay or mbstartool.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 have an third party ECU tune performed? Was the ESP module replaced ? Is the trouble code stored or current ?

 

How to do W220 ESP Variant Coding correctly:

 

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

 

CONTROL UNITS

CHASSIS

ESP

Fault Codes

Select C1511-005

 

  1. to the right it should say CURRENT or STORED

hit F8

It should show you how many time the car has ben started 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”.)

 

  1. Double click C1511-005

Read the pre conditions

hit F3

read the sequence and follow it to (hopefully) force a variant coding re-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 as a MB mech/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.

How to use BDM frame with adapters set

It’s used to update/flash ECUs, writeECM modified and programProbe holder/Dimsport aids.

The frame can work with ECM Chip Tuning Tools such as KESSKTAGFGTECHBDM 100KTM100CMD, DIMSPORT AIDS...

 

This set includes: aluminum alloy support pair, acrylic sheet (LED lamp and interface),BDM probes 4, wire 4

How to use the BDM frame aluminium:

Insert the probe to connect the BOOT on the ECU board and CNF1, the legend for the public MED17.5.2 computer board.

Applicable to open the ECU, to avoid welding jumper. In the acrylic board with LED light bar, help the case of poor light to see the hole of the board.

Jumper for the plug-in, to reduce the trouble of welding the connection, easy to connect, and can be more than a series.

LED power situation, the whole board can see clearly. LED power supply with ECU equipment with 12V power supply, connect the probe, you can disconnect the power supply, to the equipment for the

The new LED light bar interface is fixed on the acrylic plate, for the straight type.

Add a LED light to facilitate the case of poor light to see the computer board, the picture on the LED lights may be updated at any time, only for more practical.

The tip of the probe is specially designed and scalable.
