Hello everyone! Can't seem to find solution to this problem, can you please help out?

Issue:
Fault Code 471a Engine oil, critical oil mass - after clearing comes back
Can't do regen / force regen. DPF Full.
Had codes about throttle body, changed it, codes cleared.

My guess is that's why i can't do a regen, so that's why want to tackle it first before going to the shop. Anyone had this code, any clues where to look?

Thanks!

 

You have diesel in the oil so your oil needs to be changed.

 

Thank you! This have solved the issue, the code is gone.

I already did the oil change, but forgot i have to reset the oil change. Once i did that, code went away.
