Disadvantages of the VW CDGA engine

  • This engine is designed to run on gas and is afraid of low-quality fuel.
  • Pistons are often destroyed by detonation and many simply change them to forged ones.
  • Even from low-quality fuel, intake valves are covered with soot and compression drops.
  • A significant part of calls to the service station is associated with the replacement of an unreliable timing chain.
  • In the turbine, the electronic control valve most often fails, as well as the wastegate.
  • On specialized forums, they constantly complain about engine vibrations at cold temperatures and antifreeze leaks.
