Control Unit Repair (TCU) — what we cover

This section brings together 120 transmission control unit listings covering Audi, Seat, Skoda, Volkswagen, Mercedes and Porsche. Every one of them is a repair of your own unit, rebuilt and returned to the same car.

When does a transmission control unit need repairing?

The usual signs are:

  • the gearbox dropping into limp mode
  • harsh or delayed shifts
  • no drive in one or more gears
  • stored codes for the transmission control unit or its internal supply

Find your vehicle in the list above, or search by the number printed on the unit — the same hardware is often sold under several part numbers.

How the repair works

Send the unit to us and we test it, rebuild it and test it again on the bench before it goes back — usually within 2–5 working days. Replacement units require your original to be sent in for data transfer, and mechatronic units need adaptation once refitted; we tell you which applies to your part before you order. Repairs in this section carry a 24-month warranty, and replacement units 12 months. See how to order for the full process.
