Disadvantages of the Audi BDX engine

  • The most famous problem with such engines is the formation of scuffing in the cylinders.
  • The cause of scuffing is most often a faulty pouring nozzle.
  • In second place here is the stretching of the timing chains and the failure of their tensioners.
  • Phase regulators and ignition coils have a relatively modest resource.
  • Many owners have experienced oil burner or soot on intake valves.
