BMW Mini 1999 – 2006 R50 / R52 CVT Transmission Controller TCU / TCM Problems & Repairs

Transmission Control Module Repairs - BMW Mini ONEBMW Mini TCU / TCM Problems & Repairs
The BMW Mini from 1999 – 2006 (R50 / R52) was fitted with a Motorola TCU (Transmission Control Unit), also known as a TCM (Transmission Control Module). It is fitted to automatic models with the Continuously Variable Transmission (CVT).

The TCU / TCM is a very common failing part and can be very expensive to replace. Replacement units will require coding to your vehicle and come with a limited warranty – typically between 30 days and 12 months.

There are many problems associated with this type of transmission control module but the most common fault is the vehicle “jumping” into gear or not selecting the right gear. This will occur more often on a cold morning or whilst the engine is still cold.

Common Transmission Control Module Faults:

  • Not selecting correct gear (especially when cold)
  • Not going into gear at all
  • Rough gear changes
  • Warning lights on dash
  • No communication faults

Our TCU / TCM Rebuild Service
We are able to fully test & repair all types of TCU / TCM units. When rebuilding the Mini transmission modules we use new genuine OEM components to ensure that each rebuilt part will meet & exceed OE specifications. A rebuilt transmission control module (Gearbox ECU) from us will come with a Lifetime warranty and will not require any programming when being fitted back to the vehicle. The unit will be fully plug & play. We’re offering a fast, efficient & affordable repair service as an alternative solution to having the module replaced for a new expensive part. We also offer a professional fitting service if required.

  • Hi, I have R50, sometimes vehicle doesn’t shift gear atall, can’t drive more than 30km, check engine and elm error comes up on dashboard, when I reset come it helps for a while than the error comes again. When diagnosed by obd can’t access gearbox computer parameters are showen 0. What could be the problem?

    • Hi Jemal

      Thanks for the enquiry,

      This sounds like an intermittent TCM failure, it’s a very common fault, one which we have successfully tested & repaired many times before but it will need diagnosing to confirm the fault. I have sent you an email with full information and pricing.

      Kind Regards

  • Hi,

    I have a 2007 Mini Cooper S Chile Convertible autotransmission. The car starts and revs but when shifted to dr forward or reverse drive, the car wont move. Is it a TCM problem?

    • Hi John

      Thanks for the enquiry,

      There are many reasons for the vehicle to not move when put into drive/reverse. It could be a mechanical fault i.e. driveshafts & gearbox or it could be an electrical fault i.e. wiring, sensor or module. If the fault is with the TCM, we should be able to find the fault when testing the unit as we do simulate them in all conditions, including moving into drive & reverse.

      I have sent you an email with full information and pricing. If you have any questions, please reply to the email and we’ll be happy to assist you.

      Kind Regards
