What goes wrong with this engine

The faults this engine is genuinely known for — and the timing arrangement, which decides a great deal about running costs — are covered in 2.0 TDI common rail problems.

Where to find your engine code

The three or four letter code is stamped on the engine block and is usually printed in the service book. It is also stored electronically, so any diagnostic tool that talks to the engine control unit will read it back without you having to find the stamping.

The code matters more than the model year. Cars of the same age and badge were built with different engines, and the timing arrangement, common faults and correct parts all follow the code rather than the year.

VAGPULSE reads the engine code straight off the ECU, along with every stored fault and the live data behind it — so you never have to guess which engine you have. One payment, no subscription.
