Disadvantages of the VW AWM engine

  • Coking of oil in the oil supply pipe often leads to engine turbine failure;
  • Air leakage in the intake is the main culprit of floating engine speeds;
  • Ignition coils with built-in switches regularly fail here;
  • The timing chain may jump after critical wear of the controlled tensioner;
  • Electrically, the coolant temperature sensor or the mass air flow sensor is usually buggy;
  • The main reason for the formation of carbon deposits in the malfunction of the crankcase ventilation system;
  • The weak points of the motor also include: the N75 valve and the secondary air system.
