Seat Multitronic DSG / CVT Transmission Controller (TCM / TCU) Repairs

Seat Multitronic DSG Module TestingSeat DSG/CVT Transmission Control Unit Issues + Repairs
Are you having issues with your Seat Automatic Transmission Unit? Did you know that the automatic transmission fitted to Seat’s is known to become faulty? Whether it’s an automatic or semi-automatic, mechatronic or S-Tronic, a DSG (Direct Shift Gearbox) or a CVT (Continuously Variable Transmission), they are all known to have this issue.

Sometimes these faults can be repaired by a simple software update or a gearbox oil change, but unfortunately, this is not always possible and generally it is due to the fault in the Transmission Control Module (TCM) or more commonly known as the Gearbox ECU.

General DSG / CVT Transmission Controller Issues
So if your car has been suffering from the above, you may have noticed that the faults can sometimes be intermittent, however it starts to get progressively worse depending on the nature of the problem. This is due to faults that have been caused by a failed Transmission Control Module (TCM), and occasionally these can be repaired. The most common faults that have been reported by our customers regarding DSG/CVT Transmission Controllers have been listed below:

  • Gearbox Going Into Neutral
  • Not Going Into Gear
  • Loss of Reverse Gear
  • “PRNDS” Light Flashing
  • Limp Mode (Fail-Safe)
  • Power Loss
  • Jerking In/Out of Gears
  • Gearbox Fails When Hot

Common TCM associated DTC Fault Codes
Unfortunately, DSG Controllers will not always bring up warning lights or fault codes; therefore it is occasionally difficult to identify a problematic DSG Controller. We have listed the most common DTC Fault codes that have been linked with DSG Transmission Controller Unit issues below:

S-Tronic TCU RepairsGeneral Part Numbers for Seat Transmission Control Unit (TCU)
If you have researched the costs of replacing your DSG Gearbox ECU when it becomes faulty, you will probably be aware that quotes from local dealers are in the excess of £1000 + VAT, which would then also require programming at an extra cost. A standard 12 Month Warranty will also come with your new replacement part or you will have the option to replace the DSG / CVT Transmission ECU with a second-hand used part with a 30-90 day limited warranty. Again this will require programming/coding at an additional cost.

As you may expect, there are too many part numbers for the entire SEAT makes and models to list here; therefore we have compiled a broad list of the most common units that we have either exchanged or repaired for customers in the past. If you cannot see your part number on the extensive list below, then call us on 0844 847 9999 as we will still be able to test and repair your unit.

  • Hi I am facing the problem where the car is not going into gear it’s 2011 seat leon am not able to figure the part number or where to find it.

    Can you guys help?

    • Hi Kareem

      Thanks for the enquiry,

      It’s a fairly common issue on this vehicle and one we’ve been able to test for and repair. We’ve sent an email with some pricing and information but I’m afraid I cannot confirm the part number of your unit as they can vary. Your mechanic can confirm this on removing your unit but also if he has VCDS (VAG-COM) it will appear on the diagnostic system.

      Kind Regards
