Disadvantages of the VW ALZ engine
Vibrations and floating engine speeds are the most prevalent issues.
Cleaning the throttle or nozzles aids in eliminating the motor’s erratic operation.
The intake manifold’s rubber seal wear could also be the cause.
Crankcase ventilation system malfunctions rank second in terms of popularity.
An oil burn frequently starts closer to 200,000 km because of ring or cap wear.
