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.

BMW ABS pump 3451689288701: hydraulic module with control unit
If the ABS warning light is on in your BMW, one possible cause is the hydraulic module or its control unit. ABS pump 3451689288701 is a used original part, inspected before sale. 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 3451689288701 and related numbers
Below are the numbers as they appear on the labels, together with the single-string form used in catalogues:
- 3451 6892887 01 (catalogue format: 3451689288701), BMW number of the ABS pump (hydraulic part),
- 6892888, 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.
What ABS problems can point to
- the ABS stops working, although basic braking usually remains functional,
- the ABS activates for no reason during normal braking,
- the ABS warning light comes on together with the stability control warning light,
- the ABS switches itself off shortly after the engine is started.
Before buying a module, read the fault codes with a diagnostic tester. A faulty wheel speed sensor or its wiring can cause the same symptoms, and in that case replacing the pump will not help. After replacement the fault codes usually need to be cleared, and if the brake lines have been disconnected, the system must be bled.
