- The main problems are caused by air leaks due to drying gaskets;
- Even in the intake, the electrically driven geometry adjustment system often fails;
- It is necessary to clean the crankcase ventilation valve regularly or the grease will press from all the slots;
- After 200 thousand km, oil consumption is often found here due to the occurrence of rings.
