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.

Looking for a replacement for a faulty module for Skoda Fabia Volkswagen Polo? We offer a used, working comfort control module in good condition.
Vehicle and manufacturer
- Skoda Fabia Volkswagen Polo - model
- Siemens - manufacturer
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 module is sometimes described as the onboard power supply control unit (Bordnetzsteuergerät); its version depends on the equipment.
Numbers on the label
- 6Q1 937 049 / 6Q1937049 - VAG group number (OEM)
- 5WK48212A - manufacturer number (Siemens)
Fitment
Our range also includes other parts for this model with different numbers. Choose by the number on the label, not by the model alone.
Typical failure symptoms
- the system returns to normal after the battery is disconnected,
- some functions work only intermittently,
- electrical faults appear after rain or a car wash,
- warning lights on the dashboard come on for no reason.
It is worth reading the fault codes first, because many body faults come from switches or wiring rather than the module itself.
