Disadvantages of the VW AWT engine

  • The turbine often fails due to oil coking or a clogged catalyst;
  • The reason for the floating engine speed is usually air leakage somewhere in the intake;
  • Ignition coils with built-in switches have a short service life;
  • The controlled timing chain tensioner is not very reliable and may overshoot;
  • Electrical failures often occur, mainly the mass air flow sensor or the coolant temperature sensor are buggy;
  • Destruction of the crankcase ventilation membrane leads to oiling of the engine and leaks;
  • The secondary air system throws up a lot of problems, but it is most often removed.
