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.

CAS comfort module BMW
For BMW we offer a used CAS comfort module that you can match by the numbers on the list. It is working and in good condition.
How this part works
The module collects the driver's commands and distributes power to individual body circuits, so many small functions in the car depend on it. CAS (Car Access System) in BMW combines car access with engine starting, so after replacement the keys usually have to be programmed.
What a fault looks like
- the tester reports no communication with the module,
- several unrelated functions stop working at the same time,
- wipers or lights switch on by themselves,
- the car does not respond to the remote.
Before buying a module, check fuses, earth points and connectors - corrosion and damaged wiring cause similar symptoms.
