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.

When is ABS pump 3451677067601 the right choice for your BMW?
Used original ABS module with number 3451677067601 for BMW. Confirm compatibility with the number from your original pump.
Is ABS pump 3451677067601 the right part for your BMW?
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 3451677067601 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
Below are the numbers as they appear on the labels, together with the single-string form used in catalogues:
- 3451 6770676 01 (catalogue format: 3451677067601), BMW number of the ABS pump (hydraulic part),
- 3452 6770677 01 (catalogue format: 3452677067701), 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 warning light comes on after the engine is started and stays on,
- the ABS stops working, although basic braking usually remains functional,
- the ABS activates for no reason during normal braking,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
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
| Where do I find number 3451677067601 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 pump and the control unit sold separately? |
| In this listing they are a single module: a hydraulic block with the pump and valves, with the control unit attached to it. |
| Do the brakes need bleeding after replacing the module? |
| If the brake lines are disconnected during fitting, the system must be bled. The fault codes in the control unit usually need to be cleared as well. |
| 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. |
