Disadvantages of the VW ACV engine
- Most often, problems of the power supply system are discussed at specialized forums: high-pressure fuel pumps and injectors;
- Aluminum cylinder head does not tolerate overheating, watch the cooling system;
- Also, owners often complain about a knocking vacuum pump or mass air flow sensor failures;
- Once every 100,000 km, an expensive procedure for replacing belts and rollers awaits you;
- On runs over 200 – 250 thousand km, the turbine often begins to drive oil.
