Disadvantages of the Audi ABT engine

  • Most of the problems with this engine are due to the vagaries of the Mono-Motronic system.
  • Malfunctions are usually caused by air leaks or a glitch in one of the sensors.
  • In second place in popularity here are the failures of the components of the ignition system.
  • The timing belt resource is approximately 90,000 km, but when it breaks, the valves most often do not bend.
  • After 200,000 km, an oil burner often appears and hydraulic lifters knock hard.
