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 identify ABS pump 5A30BC8-01 for your BMW
If the ABS warning light is on in your BMW, one possible cause is the hydraulic module or its control unit. ABS pump 5A30BC8-01 is a used original part, inspected before sale. The listing does not state the car model or year, so we do not give them here and match the part by its numbers.
Numbers and markings on the ABS pump
You will find the numbers on the labels, while catalogues list them as a single string:
- 5A30BC8-01, BMW number in short form, without the group prefix,
- 5A30BC9-01, 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.
When an ABS module needs replacing
- 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,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- the ABS warning light comes on together with the stability control warning light.
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.
Questions and answers
| What is the difference between numbers 5A30BC8-01 and 5A30BC9-01? |
|---|
| 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. |
| 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. |
| Who makes this module? |
| The module is made by ATE. The manufacturer's name does not change the numbers you should use to match the part. |
| 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. |
