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.

What this part does
A module failure is often mistaken for faulty individual consumers: when several unrelated functions stop working at once, it is worth checking the module as well.
CAS (Car Access System) in BMW combines car access with engine starting, so after replacement the keys usually have to be programmed.
Fitment
For this model we offer several parts that differ in their numbers. The number on the label decides, not the model name alone.
Symptoms of a fault
- the central locking or locking signal does not work,
- interior lights or indicators work incorrectly,
- electric windows respond with a delay or not at all,
- communication errors appear on the dashboard.
Compare all numbers with the label on your module, because the same car model may have had several versions.
