So a few days ago the CEL popped on the dash of our 2018 Xdrive. Pulled the codes and it was P0440 (evap emission system, I love these random generic codes) along with the P0171 (system too lean). X1 was running fine as far as I could tell.
I drove it a couple of time since then (short trips, about 6 miles round trip) and today the light came back on. I also noticed when I made it back home and placed the vehicle in park, turn off the A/C. The idle started climbing, it got to about 1500RPM if not a bit higher. Turned the vehicle off and back on and the high idle went away.
I pulled the codes and the P0440 and P0171 were back along with the P0507 (Idle Air control System RPM higher than expected).

Anyone have experience with these codes on the F48? Surprisingly I was just about to take this thing in to sell and we decided the is the first vehicle we'll get rid of in our attempt to reduce the number of vehicles in our household. Maybe it doesn't want to leave us?
