Disadvantages of the Audi ASE engine

  • This motor had weak timing chain tensioners, which often led to a jump;
  • Also here, the intake manifold flaps often fell off and fell into the cylinders;
  • The remaining massive engine problems are usually related to fuel system failures;
  • Saving on oil here greatly reduces the life of turbines and hydraulic lifters;
  • Check the condition of the glow plugs or they will simply break when unscrewed.
