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
It is an electronic node of the body wiring: it receives signals from switches and sensors and then activates consumers such as lights, locks or ventilation. In VAG group cars the same model came with different module versions, so it is worth comparing the manufacturer number too.
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
- warning lights on the dashboard come on for no reason,
- electrical faults appear after rain or a car wash,

- the system returns to normal after the battery is disconnected.
Compare all numbers with the label on your module, because the same car model may have had several versions.
