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 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 CWZA.
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 CWZA.
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 CWZA.
The crankcase breather carries the vapour that forms inside the engine back to the intake, and a rubber membrane regulates the pressure.
Applies to the engine CWZA.
Repair: 80–400 EUR
The per cylinder ignition coil of these direct injection, turbocharged petrol engines fails.
Applies to the engine CWZA.
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.

2010–2015. 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.
