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.
