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.

How to identify ABS pump 5A2EBA2-01 for your BMW
This module is made by ATE. ABS pump 5A2EBA2-01 is sold together with its control unit, just as it is fitted to BMW cars. 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 to compare
The numbers from the listing, as written on the labels and as a single string:
- 5A2EBA2-01, BMW number in short form, without the group prefix,
- 5A2EBA3-01, BMW number in short form, without the group prefix,
- 10.0220-2343.4 (catalogue format: 10022023434), hydraulic block manufacturer's number.
Check the numbers on your pump and compare them with those above. If any of them differs, contact us before ordering.
What ABS problems can point to
- the ABS warning light comes on after the engine is started and stays on,
- the ABS stops working, although basic braking usually remains functional,
- the brake pedal pulses or feels uneven for no obvious reason,
- the pump motor switches on at unusual moments or runs louder than usual.
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.
