E93 Stalling after fuel up
I've read a few post with this problem and have decided to replace the Fuel Tank Breather Valve, however, my problem doesn't exactly match what others have experienced though.
The car will do a nice gentle engine stall right after filling up only about every 5th fill up. The RPM's on occasion will also jump up and down a few hundred while at a stop with the engine running and warm. Now this weekend I did about 100 or more highway miles, then i pulled off and did some city driving. The engine would either stall while at a stoplight or the RPMS would jump around inconsistently under 1000. I didn't get any codes and the gas cap is and has always been secure. Is replacing the Fuel tank breather valve a good starting point or should I be looking elsewhere? I appreciate your advice/input -Mark |

It's a fairly easy DIY and place to start - I did mine a few months ago. Previous owner mentioned having similar symptoms, I never experienced any, but I had the part and was doing spark plugs so I figured might as well do the fuel tank breather valve. No issues at all.

Sounds like my fuel tank breather valve symptoms. Would not stall/varying RPM after every fill up, was sporadic. After a while it happened very occasionally as the tank neared empty before filling. It's an inexpensive fix so worth giving it a shot first to see if that solves the issue.
