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
In BMW the CAS comfort module collects signals from switches and distributes them to consumers. We sell a used, working unit in good condition.
Symptoms of a fault
- several unrelated functions stop working at the same time,
- the car does not respond to the remote,
- the tester reports no communication with the module,
- wipers or lights switch on by themselves.
It is worth reading the fault codes first, because many body faults come from switches or wiring rather than the module itself.

What this part does
The module electronics are exposed to moisture and contact corrosion, especially when fitted in the scuttle, under the dashboard or near the doors.
CAS (Car Access System) in BMW combines car access with engine starting, so after replacement the keys usually have to be programmed.
