The launch year brought a much more modern interior and the controversial Multitronic CVT gearbox. The 1.8T timing belt is the single biggest risk — a snapped belt destroys the engine, so service history is non-negotiable.
The CVT can judder, flare or lose drive entirely. It is generally less reliable than the Tiptronic or manual alternatives.
Rev flare on acceleration, Judder pulling away, Flashing PRNDS on dash
The 1.8T engine uses a timing belt that can fail if intervals are not maintained, destroying the engine. The plastic water pump impeller can also strip.
Overheating in traffic, Heater blowing cold, Sudden engine failure if belt snaps
The 1.8T engine is prone to oil sludge if servicing has been neglected, blocking the oil pickup and starving the engine of lubrication.
Oil pressure warning, Engine knocking, Sluggish performance
Early sliding-rocker versions can suffer cam and rocker wear. Later roller-rocker engines differ, so identify the engine code and valve gear before judging the risk.
Uneven running, Progressive loss of power or top-end noise
Wires in the door rubber boot fatigue and break over time, causing central locking, window and mirror failures on the driver or passenger side.
Door window stops working, Central locking intermittent, Mirror adjustment fails
Coil packs deteriorate with age causing misfires and rough running, a common issue across VW Group petrol engines.
Misfiring at idle, Engine management light, Poor fuel economy
