Disadvantages of the Audi CEUA engine

  • This turbo engine does not tolerate low-quality fuel, oils and frequent overheating.
  • From all of the above, scuffing quickly forms in the engine cylinders.
  • Savings on lubrication reduces the already low resource of turbines to 70-100 thousand km.
  • Leaks of high-pressure fuel pumps are also often found here, and fuel from them can get into the oil.
  • Weaknesses also include active engine mounts and upper timing chain tensioners.
