Are such “vibrations” of the oil level at the oil measuring rod normal, completely safe for engine and DPF and should I not worry about it? From the oil change I drove about 8,000 km and noticed that the oil level would sometimes rise by 2-3 mm, then would go down again and again with an ever longer and faster route, although the level was never above the maximum. I have read somewhere that it is a 2.0D 136hp charm and you should only worry if the oil rises far above the maximum. The first picture shows the measured oil level before 200 km and the second one from today (the higher one). The car was standing in the garage for one week after the 200 km long distance and the second photo is in the garage after this week (maybe the water has collected in the oil tank and thus the oil level has increased)? The engine works well and evenly, the consumption is normal, DPF cleaned before 8,000 km in a special DPF washing machine and the replenished additive, difference sensor on the DPF works perfectly, AGR opens and closes, the throttle valve works well, the suction nozzle is airtight – does it make sense to take care of it? Maybe it’s just the water that collects in the oil tank and then evaporates? Maybe the oil measuring rod is poorly profiled (I have noticed that on one side of the oil measuring rod there is always more oil than on the other, as if it is in a certain wink el would have gotten into the tub).
