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.

Comfort control module Audi
For Audi we offer a used comfort control module that you can match by the numbers on the list. It is working and in good condition.
When to replace the part
- the module gets hot or smells burnt,
- random errors appear in the diagnostic memory,
- the car does not enter full sleep mode,
- a selected body function does not work although the switch is fine.
Before buying a module, check fuses, earth points and connectors - corrosion and damaged wiring cause similar symptoms.
Function in the car
The module electronics are exposed to moisture and contact corrosion, especially when fitted in the scuttle, under the dashboard or near the doors. In VAG group cars the same model came with different module versions, so it is worth comparing the manufacturer number too.

Buyers' questions
| Can a part with a different number fit as well? |
|---|
| Sometimes it can, but we do not assume that listings are interchangeable. Compare all numbers with the label on your part or ask us. |
| What should I check on delivery? |
| Check that the numbers match the description and that the connectors and housing show no cracks or corrosion. |
| Why does the number have several spellings? |
| The same label number is written with spaces, dashes or as one string. We give both forms so that it is easier to find. |
