Disadvantages of the Audi CXYA engine

  • For such a complex design, this is a very reliable motor and there are few complaints about it;
  • The main thing is not to get the engine after serious tuning; there are many of these on the market;
  • Plasma spraying on cylinder walls does not tolerate low-quality fuel;
  • Poor quality oil and long oil change intervals greatly reduce the service life of turbines;
  • There are also isolated complaints about the failure of a very expensive cooling module.
