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.

Symptoms of a worn or faulty throttle body
When the throttle body in a Volkswagen starts to fail, the most common signs are:
- carbon deposits – rough idle, engine stalling,
- worn throttle position sensor – jerking, fluctuating revs, fault code stored in the engine control unit,
- in electronic throttle bodies: failed motor or gear drive – limp mode, loss of power, engine warning light.
If cleaning does not help and diagnostics point to a throttle body or position sensor fault, replacement with a part carrying the same number is usually required. After fitting, many cars need an adaptation according to the vehicle manufacturer's procedure.
