Disadvantages of the Audi CEJA engine

  • This engine is extremely demanding on the quality of the fuel and lubricant used.
  • From bad gasoline and oil in the engine cylinders, scoring quickly forms.
  • Due to scuffing, an oil burner appears, which here is fraught with turning the liners.
  • Frequent overheating of the power unit greatly accelerates the formation of scoring.
  • After 200,000 km, timing chains often require attention and you have to remove the engine.
