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.

Is ABS pump 5B33811 the right part for your BMW?
ABS pump 5B33811 for BMW is a used original module that regulates brake pressure when a wheel starts to lock up. It is matched by the numbers on its labels, not by the car model alone. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Part number 5B33811 and related numbers
Below are the numbers as they appear on the labels, together with the single-string form used in catalogues:
- 5B33811, BMW number in short form, without the group prefix,
- 5B33812, BMW number in short form, without the group prefix.
Check the numbers on your pump and compare them with those above. If any of them differs, contact us before ordering.
When an ABS module needs replacing
- the ABS stops working, although basic braking usually remains functional,
- valve or pump motor faults are stored in the control unit memory,
- the ABS activates for no reason during normal braking,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
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.
