Disadvantages of the Audi DCUE engine

  • Despite the complexity of the design, this is a reliable turbo engine with a good service life;
  • However, it is important to find a unit that has not been subjected to serious tuning, and there are many of them;
  • And keep an eye on the quality of gasoline; there are already cases of piston destruction from detonation;
  • Plasma spraying on the cylinder walls also really doesn’t like bad fuel;
  • Saving on oil and oil change intervals greatly reduces the life of turbines;
  • Other problems are related to the formation of carbon deposits and glitches of the start-stop system.
