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 5A82CF0: hydraulic module with control unit
ABS pump 5A82CF0 for BMW is a used original module that regulates brake pressure when a wheel starts to lock up. It is matched by the numbers on its labels, not by the car model alone. The listing does not state the car model or year, so we do not give them here and match the part by its numbers. The listing gives the markings HYBRID. They help tell the module versions apart, but the full part number is what decides compatibility.
Numbers to compare
Below are the numbers as they appear on the labels, together with the single-string form used in catalogues:
- 5A82CF0, BMW number in short form, without the group prefix,
- 5A82CF1, BMW number in short form, without the group prefix.
Check the numbers on your pump and compare them with those above. If any of them differs, contact us before ordering.
Symptoms of a faulty ABS pump or control unit
- the ABS stops working, although basic braking usually remains functional,
- the ABS activates for no reason during normal braking,
- 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.
