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.

Does ABS pump 5A09E51-01 come complete with the control unit?
Used ABS pump with control unit, number 5A09E51-01, inspected before sale. Matched by the numbers on the block and sticker.
Is ABS pump 5A09E51-01 the right part for your BMW?
ABS module 5A09E51-01 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. The listing gives the markings HYBRID. They help tell the module versions apart, but the full part number is what decides compatibility.
Part number 5A09E51-01 and related numbers
Below are the numbers as they appear on the labels, together with the single-string form used in catalogues:
- 5A09E51-01, BMW number in short form, without the group prefix,
- 5A09E52-01, BMW number in short form, without the group prefix.
Matching by number is more reliable than matching by car model. Compare all the numbers and ask us if any of them does not match.
What ABS problems can point to
- 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,
- valve or pump motor faults are stored in the control unit memory,
- 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.
