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.

How to check whether ABS pump 3451846900201 fits your BMW
ABS pump 3451846900201 complete with control unit, used and inspected. Compare the numbers with the original in your car.
Used BMW ABS pump with number 3451846900201
The hydraulic block and control unit of this ABS pump form a single module that works with the wheel speed sensors in BMW cars. You will find number 3451846900201 on the label, and the full set of numbers is given in the description below. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Where to find the numbers on an ABS pump
The numbers from the listing, as written on the labels and as a single string:
- 3451 8469002 01 (catalogue format: 3451846900201), BMW number of the ABS pump (hydraulic part).
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.
When an ABS module needs replacing
- the brake pedal pulses or feels uneven for no obvious reason,
- the pump motor switches on at unusual moments or runs louder than usual,
- the ABS switches itself off shortly after the engine is started,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
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.
