Disadvantages of the VW AAZ engine
- Most of all, this diesel engine is afraid of overheating, its cylinder head cracks very often;
- In second place in terms of mass are regular fuel leaks through injection pump gaskets;
- The timing belt, according to the regulations, is changed every 60,000 km, or if it breaks, the valves will bend;
- After 200 – 250 thousand kilometers, the turbine often drives lubricant;
- The main disadvantage of such motors is their age, there is nothing alive on the secondary market.
