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 3451685057401: hydraulic module with control unit
This module is made by ATE. ABS pump 3451685057401 is sold together with its control unit, just as it is fitted to BMW cars. 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 3451685057401 and related numbers
You will find the numbers on the labels, while catalogues list them as a single string:
- 3451 6850574 01 (catalogue format: 3451685057401), BMW number of the ABS pump (hydraulic part),
- 6850575, BMW number in short form, without the group prefix.
Compare the numbers with the original pump in your car, and if any of them differs, write to us before buying.
Symptoms of a faulty ABS pump or control unit
- the ABS warning light comes on after the engine is started and stays on,
- the brake pedal pulses or feels uneven for no obvious reason,
- the ABS warning light comes on together with the stability control warning light,
- the ABS switches itself off shortly after the engine is started.
ABS faults should not be ignored, because without anti-lock protection the car brakes less well on wet or slippery roads. Diagnosis and fitting are best left to a garage with a suitable scanner.
Questions and answers
| What is the difference between numbers 3451685057401 and 6850575? |
|---|
| The module carries several numbers, because it is identified both by the car brand and by the manufacturer of the block and control unit. When matching the part, compare all the numbers. |
| Where do I find number 3451685057401 on my pump? |
| The numbers are stamped or printed on the aluminium hydraulic block, and the control unit has a separate sticker. Take a close-up photo of both places in good light. |
| Are the make and model of the car enough to choose the part? |
| No. A single model comes with different versions of the module, depending on the engine, year of manufacture and drivetrain. The most reliable reference is the number on the original pump. |
| Is this a new part? |
| No. We sell used original modules, each one inspected before sale. You will find the warranty period in the product features table. |
