Disadvantages of the VW AXZ engine
The owners’ primary grievances stem from the comparatively high fuel consumption;
In winter, condensate buildup in the exhaust system may prevent the engine from starting;
Crankcase ventilation has many issues; typically, the membrane is replaced here;
Decarbonization must be done on a regular basis because soot quickly overgrows exhaust valves;
Tensioners, timing chains, injection pumps, and ignition coils are renowned for having few resources.
