Disadvantages of the Audi CZSE engine
Since this power unit was manufactured recently, there are no records of malfunctions.
It is not feasible to replace the intake manifold separately because it is integrated into the block’s head.
With the hot side facing inward, the turbocharger is situated in the cylinder block collapse.
