- Due to contamination of the throttle or EGR valve, engine speed often floats here;
- The following also have a low resource: thermostat, pump, lambda probe and unit supports;
- After 200,000 km of run, oil consumption often appears or the chain is stretched;
- There are no hydraulic lifters and valve clearances need to be adjusted every 100 thousand km.
