  • In the first years of production, there was a burnout of the pistons due to a defect in the piezo injectors;
  • The timing chain lasts a long time, up to 300 – 350 thousand km, but its replacement is very expensive;
  • At high mileage, the particulate filter or EGR valve may become completely clogged.
