Drivetrain control units
Drivetrain control units – differential and electric drive
Here you will find used control units that belong neither to the engine nor to the gearbox, including the rear differential control unit for Audi RS4 and RS5 and the electric drive control module for Audi e-tron. We match them by the numbers on the label. Cannot see yours? Send a photo of the label or your VIN.

How to choose a drivetrain control unit
Drivetrain control units handle parts of the drive other than the combustion engine and the gearbox, for example the rear differential or the drive motors of an electric car. They depend on the model, the drive version and the software, so two cars of the same make may have different units. Compare the number on the housing with the number in the listing.

What to look out for
A used unit may still hold the data of the previous car, so coding or matching may be needed after replacement. Work on a high-voltage system, as in the Audi e-tron, should be carried out by a qualified workshop. Ask us before buying if you are not sure.
Frequently asked questions
| Is a drivetrain control unit the same as an engine control unit? | No. The engine control unit handles ignition and injection, while the units in this category handle other parts of the drive, such as the rear differential or the drive motors of an electric car. Engine control units are in a separate category. |
|---|---|
| Is the car model enough to choose the part? | No. The same model may have different versions of a part depending on the drive, equipment and year. What counts is the number on the label or in the listing. |
| What should I send so you can check the fit? | A photo of the label or housing with the numbers visible, plus your VIN or the make, model, year and drive of the car. On that basis we check whether we have a matching version. |
