Disadvantages of the VW CAVA engine
- Many engine problems are related to detonation due to the quality of the fuel consumed.
- Bad gasoline simply cracks pistons and many replace them with forged ones.
- The intake valves here quickly overgrow with soot and the compression in the cylinders drops.
- The timing chain has changed many modifications, but it rarely runs more than 100,000 km.
- The turbine often fails the electronic control valve, as well as its wastegate.
- The source of the coolant leak is most often located in the intercooler area.
