Disadvantages of the QG18DD engine
- This engine is extremely demanding on fuel quality and has a very gentle high pressure fuel pump;
- Regularly, the motor experiences traction failures due to the fault of another clogged filter;
- The timing chain is pulled out pretty quickly, sometimes it does not even reach 150,000 km;
- On runs over 100 thousand km, a progressive oil burn often begins;
- There are cases of destruction of the catalyst, the crumbs of which enter the cylinders.
