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.
In VAG group cars the module is sometimes described as the onboard power supply control unit (Bordnetzsteuergerät); its version depends on the equipment.
Fitment
Before ordering, compare number 3C0937049AD with the label on the module removed from your Volkswagen. A matching number is the most reliable way to choose the part.
Symptoms of a fault
