Disadvantages, breakdowns and problems of CGWA
Most often, owners of A8 with such an engine complain about increased oil consumption.
The reason is usually scuffing from catalyst crumbs that are drawn into the cylinders.
Since there are no check valves for the oil channels of the cylinder head, they crack on the cold chain
Another culprit for the noise of the timing chains here can be the wear of the hydraulic tensioner.
The pump, high-pressure fuel pump have a low resource, and muffler corrugations often burn out
