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 3451846901701: hydraulic module with control unit
This module is made by ATE. ABS pump 3451846901701 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.
Where to find the numbers on an ABS pump
You will find the numbers on the labels, while catalogues list them as a single string:
- 3451 8469017 01 (catalogue format: 3451846901701), BMW number of the ABS pump (hydraulic part),
- 8096587, BMW number in short form, without the group prefix.
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 ABS stops working, although basic braking usually remains functional,
- valve or pump motor faults are stored in the control unit memory,
- the pump motor switches on at unusual moments or runs louder than usual,
- 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.
Questions and answers
| 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. |
| Does a lit ABS warning light always mean a faulty pump? |
| No. Read the fault codes first, because the cause may be a wheel sensor, its wiring or too low a supply voltage. |
| 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. |
