Disadvantages of the VW AUC engine

  • This reliable unit as a whole regularly worries its owners on trifles.
  • The ignition system delivers the most problems: candles, coil, high-voltage wires.
  • It is necessary to carefully monitor the condition of the belt, since when it breaks, the valves bend.
  • In winter, the crankcase ventilation system often freezes and oil presses through the dipstick.
  • Camshaft position sensor and antifreeze temperature sensor often fail.
