Vehicle-specific file service
Mercedes-Benz ECU & TCU File Service
Mercedes-Benz ECU and TCU file service for supported CDI, MED, MD1, CRD and VGS control units with secure workshop delivery.
Mercedes-Benz file work covers a broad range of diesel, petrol and transmission controllers. CDI and CRD diesel systems, MED petrol ECUs, newer MD1 units and VGS transmission controllers each require accurate identification and an appropriate read method.
The portal groups vehicle data, control-unit information, original files and workshop notes in one request. This reduces confusion when a vehicle family has multiple ECU variants or software updates.

Frequently asked questions
Why is ECU identification important on Mercedes-Benz vehicles?
Similar vehicle descriptions can use different CRD, EDC, MD1 or MED controllers. Identification prevents the request from being matched to the wrong ECU family.
Can ECU and TCU requests be submitted together?
Yes, where supported. Include separate original reads and identification data for each controller.
