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: numbers 3451677606601 and 3452677606701
ABS module 3451677606601 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.
Part number 3451677606601 and related numbers
The numbers as written on the labels and as a single string, the way catalogues list them:
- 3451 6776066 01 (catalogue format: 3451677606601), BMW number of the ABS pump (hydraulic part),
- 3452 6776067 01 (catalogue format: 3452677606701), BMW control unit number,
- 10.0961-0851.3 (catalogue format: 10096108513), control unit number.
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.
Symptoms of a faulty ABS pump or control unit
- the ABS stops working, although basic braking usually remains functional,
- the ABS activates for no reason during normal braking,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- 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.
