Disadvantages of the VW AXQ engine

  • It’s an aluminum block, but scuffing is rare with normal maintenance;
  • But if you save on oil and allow frequent overheating of the engine, then they will appear;
  • The main problems here are associated with unreliable timing chain tensioners;
  • You also need to monitor the condition of the timing belt, since with its breakage the valves bend;
  • Lubrication leaks often occur here, and especially at the junction of the motor and gearbox.
