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 EGR cooler cools the recirculated exhaust gas before it enters the intake again, and coolant flows through it while it does so.
Applies to the engine DEUA.
Repair: 600–1,500 EUR
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 DCPC.
On short urban trips the particulate filter cannot burn through.
Applies to the engine DETA, DETB, DEUA.
The most common source of faults on the longitudinal 7 speed S tronic that replaced the DL501 (0CJ / 0CK / 0CL) is the mechatronics unit as well.
Applies to the transmission DL382.
On AdBlue (SCR) diesels the NOx sensor after the catalyst ages, and the tip of the dosing valve crystallises.
Applies to the engine DETA, DETB, DEUA.
The tension of the piston rings is too low, so oil gets into the combustion chamber.
Applies to the engine DNPA.
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 DNPA, DAXB, DLGA.
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 DAXB, DLGA, DNPA.
7 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
2017–2024. 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.
The fault list is.
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.
