Disadvantages of the Audi BDV engine

  • The main complaints of car owners with this engine are related to oil and antifreeze leaks;
  • It is worth at least once to overheat the engine well and modest leaks turn into streams;
  • Hydraulic lifters and chain tensioners quickly fail from poor lubrication;
  • The cause of unstable engine operation is usually a dirty throttle or idle valve;
  • On long runs, the electrician often fails: sensors, ignition coils and lambdas.
