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.

Numbers and markings on the ABS pump
The numbers from the listing, as written on the labels and as a single string:
- 3451 5A1BBC4 01 (catalogue format: 34515A1BBC401), BMW number of the ABS pump (hydraulic part),
- 5A1BBC5, BMW number in short form, without the group prefix.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
What can point to an ABS pump failure
- the ABS warning light comes on after the engine is started and stays on,
- the brake pedal pulses or feels uneven for no obvious reason,
- the pump motor switches on at unusual moments or runs louder than usual,
- the ABS activates for no reason during normal braking.
It is worth reading the fault codes and checking the sensor wiring before replacement. Fitting and bleeding the brake system are usually carried out by a garage with the right equipment.
