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, CSWB, DCPE.

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.

Applies to the engine CRTC, CSWB, DCPE.
On short urban trips the particulate filter cannot burn through.
Applies to the engine DETA.
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.
The internal springs of the flywheel tire, and the two discs knock against each other.
Applies to the engine DETA.
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 CYRB, DDWA.
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, DDWA.
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 CYRB, DDWA.
4 more faults belong to this generation. On the version page, only the ones that apply stay.
Engines and transmissions in this generation
A fault is often tied to the engine, not to the whole generation. You find the engine code in the registration document.

Common questions
2015–2019. 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.
