Disadvantages, breakdowns and problems of the CDRA internal combustion engine
Saving on the quality of fuel and oils here often leads to the formation of scoring
Many engine problems are related to coking due to the direct injection system.
Around 200 km, timing chains can already stretch, and replacing them is difficult and expensive
The plastic intake manifold often cracks and loses its tightness
Another weak point of this motor is the oil separator and ignition coils.
