Disadvantages of the VW ACV engine

  • 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.
