Disadvantages of the Audi CREC engine
The use of new cast-iron sleeves reduced the problem with scuffing to almost nothing.
However, catalysts from low-quality fuel are destroyed just as quickly.
The cause of severe crackling of timing chains is most often the wear of hydraulic tensioners.
In difficult operating conditions, the capricious high-pressure fuel pump quite often fails.
