Mein Auto:
X3 fuel trim

I have reset ADP. Drove vehicle till reset but I come down with 2883 and 2882 but in freeze frame p code is P0175 witch is a rich code adaptions reading negative -5.89 b1/ -8.0 b2 mass is reading 22kg/h which in my mind way to high should be about 14to16 pulled a plug appears burning lean.
Tried another mass (ati) ,when first setting adaptions came down to 14.1 kg/h but still got a2883 b2 let it set over night recked actual values mass again reading 22kg/h thinking possible DME ?
Needed some input , found no intake leaks, already smoked
Thanks
