- Multitronic CVT FailureSerious
The CVT can judder, flare or lose drive entirely. It is generally less reliable than the Tiptronic or manual alternatives.
- 1.8T Timing Belt / Water Pump FailureSerious
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.
- Oil Sludge BuildupSerious
