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.

What does number 6791521 on an ABS pump mean?
Used original ABS module with number 6791521 for BMW. Confirm compatibility with the number from your original pump.
BMW ABS pump: numbers 6791521 and 6778164
ABS module 6791521 is used and has been inspected before sale. It is intended for BMW cars, but whether it fits is decided by comparing the numbers with the original part in your car. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Numbers and markings on the ABS pump
The numbers as written on the labels and as a single string, the way catalogues list them:
- 6791521, BMW number in short form, without the group prefix,
- 6778164, BMW number in short form, without the group prefix,
- 10.0960-0834.3 (catalogue format: 10096008343), control unit number.
Compare the numbers with the original pump in your car, and if any of them differs, write to us before buying.
What can point to an ABS pump failure
- the brake pedal pulses or feels uneven for no obvious reason,
- 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.
First check the wheel sensors, their wiring and the supply voltage. Only a fault code pointing to the module justifies replacing the pump. After fitting, clear the fault codes and, if necessary, bleed the brake system.
