Disadvantages of the VW AEY engine
The low power of this diesel engine is more frequently criticized on specialized forums than other issues; the injection pump, which is dependable but frequently fails with age, is the primary cause of breakdowns;
Nozzles start to pour over time, but only nozzles can be changed;
Oil leaks are common, and the heat exchanger and valve cover are weak points. After 250,000 kilometers, the piston rings may already be lying down, and lubricant consumption is evident.
