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 3451677714901 the right part for your BMW?
If the ABS warning light is on in your BMW, one possible cause is the hydraulic module or its control unit. ABS pump 3451677714901 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.
Numbers to compare
The numbers from the listing, as written on the labels and as a single string:
- 3451 6777149 01 (catalogue format: 3451677714901), BMW number of the ABS pump (hydraulic part),
- 3452 6777150 01 (catalogue format: 3452677715001), BMW 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.
What can point to an ABS pump failure
- 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,
- brake fluid leaks from the hydraulic block, which requires immediate action.
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.
