The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

How do I recognise the 5WP42690AA ECU from a Golf 1.6 TDI?
On this module's label the number 5WP42690AA is written as 5WP42690 AA, with VW number 03L906023MK next to it. Another used, fully working unit from a Golf 1.6 TDI – available in a locked or unlocked version.

If your Golf 1.6 TDI will not start or the diagnostic tool cannot see the engine computer, check whether the car has the 03L906023MK ECU. This module manages fuel injection, rail pressure and boost. We offer several units with the same numbers – this listing is for one of them.
How to identify this module
- 5WP42690AA – number from the label (5WP42690 AA), Siemens VDO / Continental numbering
- 03L906023MK – Volkswagen part number, version MK
You will find the label on the ECU casing. Compare both numbers – if the VW number has a different final letter, the module may have different software.
When the ECU stops working
- the starter turns but the engine will not fire,
- internal ECU faults are stored in the memory,
- the car loses power and goes into limp mode,
- the fault appeared after water ingress or a voltage spike.
Before replacing it, inspect the plug and the wiring loom – bent pins or corrosion produce similar symptoms.
Which versions we offer
You can buy this unit unlocked – prepared by us before dispatch, usually within 1–2 working days – or locked, with the immobiliser and data from the previous vehicle, for workshops that carry out the unlocking, programming and adaptation themselves.
Whether PIN / CAR PASS, a Virgin version, IMMO OFF, auto programming or clone can be used depends on the part number, software and immobiliser – we will confirm this before you buy. You will find a description here: ECU options.
