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.
