Disadvantages of the VW AUQ engine

  • The main reason for the unstable operation of the engine is the constant air leakage through the crankcase ventilation;
  • Numerous branch pipes of the crankcase ventilation system simply crack;
  • A low resource has a hydraulic chain tensioner, which plays the role of a phase regulator here;
  • Often there are leaks of antifreeze from the tee of the cooling system and failures of the coolant temperature sensor;
  • Ignition coils with built-in switches fail very quickly.
