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 5A7E640-01 fits your BMW
Used original ABS module with number 5A7E640-01 for BMW. Confirm compatibility with the number from your original pump.
Used BMW ABS pump with number 5A7E640-01
This is a used original ABS pump with a control unit for BMW cars: an aluminium hydraulic block with valves and a pump motor, with the electronics bolted to it. The main number is 5A7E640-01, and the other numbers from the labels are listed 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.
Part number 5A7E640-01 and related numbers
The numbers from the listing, as written on the labels and as a single string:
- 5A7E640-01, BMW number in short form, without the group prefix,
- 5A7E649-01, BMW number in short form, without the group prefix.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
What can point to an ABS pump failure
- the ABS warning light comes on after the engine is started and stays on,
- 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,
- the ABS switches itself off shortly after the engine is started.
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.
