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.

How does the 022906032BG ECU differ from the 022906032Q?
Both VW numbers share the same prefix, but the unit offered here is a Bosch ME7.1.1 with the number 0261207350, whereas the 022906032Q is a Bosch ME7.1 with the number 0261206819. So what counts is the full number including the letters, not just its first part.
Engine Control Unit Volkswagen Bosch ME7.1.1 022906032BG 0261207350
This used petrol engine control unit is a Bosch ME7.1.1 from the Motronic family. It controls injection and ignition in a Volkswagen, and its identity is confirmed by two numbers: 022906032BG, assigned by Volkswagen, and 0261207350, assigned by Bosch. The unit is in working order and in good condition.
How to identify this ECU
- 022906032BG – VW number
- 0261207350 – Bosch number, shown on the label as 0 261 207 350
- ME7.1.1 – Bosch Motronic family designation
When matching, the 022906032 prefix is not enough – the letters BG at the end denote a specific hardware or software version. Check both numbers on the sticker of your ECU.
Symptoms that point to the ECU
- signs of moisture, corrosion or overheating on the connector and casing,
- injectors not being triggered during cranking,
- the engine cranks but will not start – no spark or injection even though the coils and injectors are fine,
- limp mode with reduced power that the sensor readings do not explain.
Also check that the connector is not damp and that the power supply wires are not broken.
