A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

Is ABS pump 6785442 the right part for your BMW?
ABS pump 6785442 for BMW F10 is a used original module that regulates brake pressure when a wheel starts to lock up. It is matched by the numbers on its labels, not by the car model alone. According to the listing, the pump comes from the BMW F10 model.
Where to find the numbers on an ABS pump
You will find the numbers on the labels, while catalogues list them as a single string:
- 6785442, BMW number in short form, without the group prefix,
- 0 265 250 546 (catalogue format: 0265250546), hydraulic block manufacturer's number,
- 0 265 960 449 (catalogue format: 0265960449), control unit number.
Compare the numbers with the original pump in your car, and if any of them differs, write to us before buying.
When an ABS module needs replacing
- valve or pump motor faults are stored in the control unit memory,
- the pump motor switches on at unusual moments or runs louder than usual,
- the ABS switches itself off shortly after the engine is started,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
ABS faults should not be ignored, because without anti-lock protection the car brakes less well on wet or slippery roads. Diagnosis and fitting are best left to a garage with a suitable scanner.
Questions and answers
