Salutations, everybody!
Since the DPF was planned, I've been experiencing problems with oil level. I removed the old oil and replaced it with fresh, but the problem reappears after just fifteen kilometres of driving.
Once you reach 15 kilometres, the mechanic says there's no way that 0.5 litres of diesel can reach the engine.


Is it familiar to you? In that case, how did you fix it?
Much obliged.

Then which one are you referring to? DPF, Adblue, or EGR? Removing a DPF is more effective than simply mapping it. Your oil level will be unaffected by those modifications, even though your car is now unlawful. He's right, though. Half a litre doesn't seem to mean much when it comes to electronic oil level sensors. It appears from your dashboard that you slightly overfilled it, which might be an issue with dervs, but as long as you put the correct amount in, it should be fine. Oh, my goodness, a dipstick!

It is well-known that questionable dpf disable maps are resulting in constant regeneration, which in turn causes oil fuel contamination....

Yeah, but I just changed the oil and went fifteen kilometers—the level was in the medium and gradually rose to the high.
Additionally, the problem just goes away and the level shows as usual when I drive again after stopping for ten to fifteen minutes.
Consequently, a very unusual

I can relate to missing my dipstick as well. (M274 petrol to OM654 diesel).

There will be more oil in the sump after a few minutes of running the engine at a heated temperature since oil expands with heat. The level will be higher when the engine is warm.

My initial reaction was to say the same thing, but then I realised it was clear.
