Vehicle runs fine, but I just threw a P0444 code today.
I couldn't find much of anything on that generic code other than at this link:
https://www.carobdcode.com/p0444-bmw...e-circuit-open
I'll start by replacing the fuel cap as I didn't love the fit of the aftermarket one on the thing when I bought it in Dec anyway. Plenty of emissions issues could be with that iffy cap...
If the gas cap ain't it, that link suggests to me it might be worth trying the $95 part (vapor canister purge solenoid) before taking it for a more complete diagnosis.
Any other pre-service shop suggestions?
Thanks!
