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.

BMW ABS pump: numbers 7707617 and 10021450034
If the ABS warning light is on in your BMW, one possible cause is the hydraulic module or its control unit. ABS pump 7707617 is a used original part, inspected before sale. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Part number 7707617 and related numbers
The numbers as written on the labels and as a single string, the way catalogues list them:
- 7707617, BMW number in short form, without the group prefix,
- 10.0214-5003.4 (catalogue format: 10021450034), hydraulic block manufacturer's number,
- 10.0961-0847.3 (catalogue format: 10096108473), control unit number.
Compare the numbers with the original pump in your car, and if any of them differs, write to us before buying.
Symptoms of a faulty ABS pump or control unit
- the ABS activates for no reason during normal braking,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- the ABS warning light comes on together with the stability control warning light,
- 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.
