Disadvantages of the VW AGZ engine
- All VR5 power units are famous for their rather high fuel and lubricant consumption;
- The timing chain does not have a very high resource, and its replacement is difficult and expensive;
- The reason for the unstable operation of the engine is usually air leakage or dirt on the throttle;
- Also, the engine often worries about electrics: various sensors fail;
- The valve cover here is combined with a gasket and changes entirely in case of oil leakage.
