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 can I check whether the 03C906027D ECU will fit a Sharan 1.4 TSI?
Read the number on the sticker of your ECU and compare it with 03C906027D and with the Bosch number 0 261 S06 037. This used, working module comes from a Volkswagen Sharan 1.4 TSI.
Engine Control Unit Volkswagen Sharan 1.4 TSI Bosch 03C906027D 0261S06037
The 1.4 TSI engine in the Volkswagen Sharan is a turbocharged petrol unit, and this Bosch ECU oversees its fuel injection, ignition and throttle operation. The module's VW number is 03C906027D and its Bosch number is 0261S06037. Smooth engine running depends on the ECU working properly, as does whether the car goes into limp mode. A module fault can show up in very different ways – from a no-start to a sudden loss of power on the road.
Numbers of this ECU
- 03C906027D – VW part number
- 0261S06037 – Bosch number, 0 261 S06 037 on the label
A Bosch number with the 0 261 prefix refers to petrol engine ECUs. When swapping, the full VW number is what matters most – the letter D at the end indicates the version and must not be ignored.
Possible failure symptoms
- no start with a working fuel system,
- limp mode and lack of power when accelerating,
- the engine warning light is on and the faults return after clearing,
- the ECU does not respond in diagnostics.
Before replacing it, check the module's power supply, earths and connector – these are the first things worth ruling out.
Versions available
Choose locked if a workshop will unlock, program and adapt the ECU itself – the module then contains the data and immobiliser of the donor car. We prepare the unlocked version before dispatch, usually within 1–2 working days.
Possible methods include PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone, but their availability depends on the number, software and immobiliser. Please ask before buying. More on the ECU preparation options page.
