What to watch for
The list covers the generation, the engines and the transmissions. Once you pick the version, only the faults that apply to it stay.
The timing chain of the longitudinal V6 diesel runs at the back of the engine, on the gearbox side, so replacing it means taking out the engine or the gearbox.
Applies to the engine CRTC, CVZA, CZZA and 3 more.
The four groups of parts in the air suspension (compressor, valve block, ride height sensors, air springs) work together, and any weak link causes a fault message, an uneven ride height or a car that settles.
It can affect every car in this generation.
The internal springs of the flywheel tire, and the two discs knock against each other.
Applies to the engine CZAC.
The combined housing of the water pump and the thermostat is plastic, and it is bolted directly to the hot engine block.
Applies to the engine CVJA, CYMC, CYRB.
The crankcase ventilation (PCV) of the third generation 1.8/2.0 TSI fails less often than its predecessors, but it is not faultless.
Applies to the engine CYRB.
With direct injection the fuel does not wash the intake valves: the petrol goes into the cylinder, not behind the valve.
Applies to the engine CVJA, CYMC, CYRB and 1 more.
The vanes of the variable geometry turbo are glued together by soot and oil arriving through the EGR.
Applies to the engine CZAC.
The G62 sensor tells the engine control unit how hot the coolant is.
Applies to the engine CZAC, CREC.
2 more faults belong to this generation. On the version page, only the ones that apply stay.
The manufacturer fixes these for free at a franchised dealer. Ask with the VIN whether it was done. The list covers the whole generation. We did not filter it by model year. Some apply only to a narrower production window.

Common questions
2015–2024. The changeover year can fall in two generations. If the listing is from that year, look at the neighbour too.
No. It depends on the engine and the transmission too.

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.
