Disadvantages of the VW BRN engine

  • This engine is afraid of overheating, so keep an eye on its cooling;
  • Constant overheating and low-quality oil contribute to the formation of scoring;
  • Seizures in the cylinders lead not only to knocking, but also to impressive oil consumption;
  • A decrease in lubrication pressure in the system often results in turning the liners;
  • After 200,000 km, timing chains can stretch, and to replace them, you need to remove the engine.
