Mercedes · Control units
For a Mercedes enquiry, the chassis series is useful but not sufficient. Include the exact control unit part number, hardware version and target vehicle. Support must be checked at unit level, including later coding and commissioning.

W204, W211, W221, the Sprinter W906, the Vito W639 and the W212 built up to 03/2013 use FBS3. FBS4 started with the W212 built from 04/2013, the C/A207 from 07/2013 and the CLS W218 from 09/2014, and applies throughout to W205, W213, W222 and later series. The production date, not the registration date, is decisive.
Why the series alone is not enough
Within one series, part numbers, hardware versions and software levels differ. Whether a used unit can be renewed and commissioned is therefore always checked for the specific unit.
Units with commissioning on the vehicle
Mercedes ABS/ESP, airbag/SRS and SAM units are commissioned only with the vehicle here. For other units, we agree with you before shipping who carries out the commissioning on the target vehicle.
Please include
The exact ECU entry is decisive. Vehicle series, brand names and examples are not blanket approval. Unconfirmed entries remain subject to assessment.
- Vehicle model, year and target vehicle VIN if available
- Original and donor part numbers and hardware identifiers
- Symptoms, fault codes and previous work
- Country, return postcode and whether you are a workshop
