Disadvantages of the Audi CREC engine
Scuffing was virtually eliminated with the use of new cast-iron sleeves.
Catalysts made from inferior fuel, however, decompose equally quickly.
The most common cause of severe timing chain crackling is hydraulic tensioner wear.
The unpredictable high-pressure fuel pump frequently fails under challenging operating conditions.
