Disadvantages of the Audi CAJA engine

  • The most famous problem of the motor is the oil burner due to scuffing in the cylinders;
  • Another cause of lubricant consumption is often a defective oil separator;
  • Cracking when starting the engine hints at the critical wear of the timing chain tensioners;
  • The low resource here is different pump and high pressure fuel pump;
  • After 100,000 km, catalysts often pour out, and their particles are drawn into the cylinders.
