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 CUNA.
Repair: 600–1,500 EUR
On these engines the oil pump is driven by its own small toothed belt, and that belt runs in the hot engine oil.
Applies to the engine CUNA.
Repair: 200–600 EUR
On short urban trips the particulate filter cannot burn through.
Applies to the engine CUNA.
The crankcase breather of the five-cylinder 2.5 TFSI leads the oil vapour into the intake, and the stub of the diverter valve sits directly next to it.
Applies to the engine DAZA, DNWA.
Repair: 200–600 EUR
The solenoids of the mechatronics unit wear out: slow or harsh shifting, then limp mode.
Applies to the transmission DQ250.
The tension of the piston rings is too low, so oil gets into the combustion chamber.
Applies to the engine DKTB, DNPA.
The 7 speed, wet clutch DSG that replaced the DQ250 in the MQB models (0GC / DQ381) is vulnerable from the mechatronics side.
Applies to the transmission DQ381.
On the EA288 the coolant pump is demand-controlled, and after replacement the cooling circuit cannot be filled the old way.
Applies to the engine CUNA.
10 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.
A12/00137/21Safety recallInjuriesno date · EU Safety GateA fixing bracket on the curtain airbag module between the gas generator and the airbag may not be installed correctly. In the event of the airbag being deployed as part of a possible accident event, the airbag would not be filled correctly. As a result, it would not be possible to ensure a sufficient restraining effect for the user, increasing the risk of injuries.
Remedy: Type of economic operator taking notified measure(s): Manufacturer Category of measure(s): Recall of the product from end users Date of entry into force: Unknown
A12/00541/22Safety recallBurns, Fireno date · EU Safety GateDesign engine covers installed on all affected vehicles could detach from their fixings depending on the conditions of use (e.g. very sporty driving, or poor road surfaces) and their age. A loose engine cover could come into contact with the hot area of the exhaust gas turbocharger, increasing the risk of burns or fire. The product does not comply with the Regulation on the approval and market surveillance of Motor Vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles.
Remedy: Type of economic operator taking notified measure(s): Manufacturer Category of measure(s): Recall of the product from end users Date of entry into force: Unknown
A12/00690/20Safety recallFireno date · EU Safety GateA bracket mounted on the car body side can damage the fuel tank in the event of a crash. Consequently, fuel may leak close to a source of ignition, increasing the risk of fire.
Remedy: Type of economic operator taking notified measure(s): Manufacturer Category of measure(s): Recall of the product from end users Date of entry into force: Unknown

Common questions
2014–2023. 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.
