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.

Where to find number 5A7F0A7-01 on BMW ABS pumps
Used ABS pump with control unit, number 5A7F0A7-01, inspected before sale. Matched by the numbers on the block and sticker.
How to identify ABS pump 5A7F0A7-01 for your BMW
ABS module 5A7F0A7-01 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 to compare
The numbers from the listing, as written on the labels and as a single string:
- 5A7F0A7-01, BMW number in short form, without the group prefix,
- 5A7F0A8, BMW number in short form, without the group prefix,
- 10.0220-2852.4 (catalogue format: 10022028524), hydraulic block manufacturer's number.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
Symptoms of a faulty ABS pump or control unit
- the brake pedal pulses or feels uneven for no obvious reason,
- valve or pump motor faults are stored in the control unit memory,
- the ABS warning light comes on together with the stability control warning light,
- the ABS switches itself off shortly after the engine is started.
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.
Questions and answers
| Where do I find number 5A7F0A7-01 on my pump? |
|---|
| The numbers are stamped or printed on the aluminium hydraulic block, and the control unit has a separate sticker. Take a close-up photo of both places in good light. |
| Which car model does this pump fit? |
| The listing does not state a model or year, so confirm compatibility with the number from the original pump in your car, or send us a photo of it. |
| Does a lit ABS warning light always mean a faulty pump? |
| No. Read the fault codes first, because the cause may be a wheel sensor, its wiring or too low a supply voltage. |
| What condition is this pump in? |
| It is a used original part, inspected before sale. You will find the warranty period in the product features table. |
