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.
