Disadvantages of the VW CAYC engine
Although this diesel engine is thought to be very dependable, it dislikes poor fuel.
As a result, the majority of his issues have some connection to piezo injector malfunctions.
It frequently presses grease from beneath the plastic valve cover, even in this engine.
Although the timing belt lasts a long time, it needs to be maintained because if it breaks, the valves will be bent.
Additionally, an EGR valve and a particulate filter cause a lot of issues for owners.
