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.
A few seconds of chain rattle on a cold start, later a permanent noise; the chain stretches and the tensioner does not hold it.
Applies to the engine CAXA, BLG, BMY.
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 CAYC.
Repair: 200–600 EUR
With the 2008 EA888 VW switched from a belt to a chain, and the tensioner of the first two generations turned out weak: as the ratchet mechanism ages it does not hold its position when the engine stops and the oil pressure disappears.
Applies to the engine CAWB, CCTA.
The PD (pump injector) unit is held in the cylinder head by a single side bolt.
Applies to the engine BJB, BKC, BLS and 5 more.
The high pressure fuel pump is driven by the camshaft through a cam follower.
Applies to the engine BAG, BLF, BLP and 8 more.
On this engine the water pump is driven by the timing belt, and the plastic impeller of the pump, along with its electronically controlled shut-off ring, is the weak point: the ring sticks, and the impeller separates from the shaft or disintegrates.
Applies to the engine CAYC.
The same layout as in the naturally aspirated FSI, only in the turbocharged 2.0: the high pressure fuel pump is driven by the camshaft through a flat cam follower that relies on an oil film.
Applies to the engine BWA, AXX, BYD.
The Aisin automatic of the transverse engine VAG models locks the torque converter across a wide slip range, which gains on fuel consumption but loses on the life of the friction lining.
Applies to the transmission AQ250.
16 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.

2003–2008. 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.
