BMW 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.
