Faster DPF regeneration

You mean you did a new program in the car computer with dpf OFF etc.... If so... and it gives you regenerations by raising the oil level... The programmer has made a mistake.... I have also heard from others that the programmers didn't make it.... He wants you to find the right expert to make your car normal.... Also there is a possibility that the programmer will manage not to do regenerations and the oil level will go up... Probably to blame the injector that is corrupted on the edge, and doesn't spray properly... I personally haven't heard of this as a script... If the developer does it right... The injectors even modified on the edge from the regens... won't upload the oil level...
No programming done to my car yet…I’m sorting the myriad of issues out first. Injectors and walnut blast done and next up is the shot motor mounts. The oil level rising was definitely due to stopping mid regen, when you turn off the vehicle mid regen the excess fuel injected for the DPF gets into the sump due to gravity.

You can see on the maintenance section on the infotainment that your oil life drops by 10% each time you turn it off while regenerating.

Leaky seals may well have contributed though.
 
Injectors went on mine as well. Didn’t have any codes, but it’s odd your oil level isn’t going up. Mine was regenerating every 40/60 miles which went up to around 200 after the change, no codes. Because it was regenerating so much I was often stopping it mid regen and oil levels went up. I didn’t go to main dealer and got it done for about 1.9k.
