Disadvantages of the VW AYH engine
- The most famous problem with this engine is the short life of the turbines;
- Also, the timing gear mechanism is not the highest resource here;
- Cylinder wall coating does not tolerate fuel savings and often crumbles;
- By 150,000 km, unit-injectors and a tandem pump often already leak through the seals;
- Other weak points of this diesel engine include the generator and the air conditioning clutch.
