- Ignition coils with built-in switches have a short service life;
- The controlled timing chain tensioner is not very reliable and may overshoot;
- Electrical failures often occur, mainly the mass air flow sensor or the coolant temperature sensor are buggy;
- Destruction of the crankcase ventilation membrane leads to oiling of the engine and leaks;
- The secondary air system throws up a lot of problems, but it is most often removed.
