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.

Function in the car
The module collects the driver's commands and distributes power to individual body circuits, so many small functions in the car depend on it. In VAG group cars the same model came with different module versions, so it is worth comparing the manufacturer number too.
Matching by numbers
Our range also includes other parts for this model with different numbers. Choose by the number on the label, not by the model and year alone.
Numbers to compare
- 5DK009064-01 / 5DK00906401 - manufacturer number (Hella)
- 3C0 959 433 H / 3C0959433H - VAG group number (OEM)
What a fault looks like
- door signalling works incorrectly,
- nothing happens when settings are changed,
- the battery drains overnight for no obvious reason,
- the interior lighting does not switch off.
Inspect the module connectors: green or burnt pins cause symptoms similar to faulty electronics.
