Disadvantages of the VW BMY engine

  • This engine does not tolerate bad fuel, intake valves quickly become overgrown with soot.
  • Due to detonation, pistons often burn out here and it is better to replace them with forged ones.
  • After 100 – 150 thousand kilometers, rings usually lie down and oil consumption begins.
  • The control valve and wastegate of the turbocharger have low reliability.
  • The timing chain resource rarely exceeds 100,000 km, sometimes it runs even half as much.
  • Owners also complain about antifreeze leaks, most often in the intercooler area.
  • An unpleasant feature of the unit are periodic vibrations during cold start.
