- As a result of any decrease in the level of antifreeze, it immediately breaks through the cylinder head gasket;
- It is very important to change the fuel filter on time or you will have to repair the injection pump;
- When replacing a fuel filter, owners often break its expensive glass;
- Every 100,000 km, an expensive valve clearance adjustment procedure awaits you;
- At very long runs, cases of prechambers falling into cylinders were recorded.
