    Unfortunately, the new gas cap didn't fix it.

    In addition to the fill up scenario when it stalls every time, I also have a cold engine scenario during the first 15 minutes where it may stall during idle, but not consistently. It will idle normally for awhile, then the rpm might suddenly dip sharply and the engine may recover by itself or it may stall. It's almost like there was a very brief interruption of fuel.

    My repair shop thinks it might be the fuel pump. They plan to hook up a fuel pressure gauge and watch what happens when it stalls.

    I guess MINI calls it a "fuel tank breather valve". I'll mention it to the shop.

    If you top off past the vapor return line on top of you filling tube, the overflow will make its way to he charcoal canister and plug your vapor return line.

    Sorry for joining in late, but I had to change that valve on my car about a year and a half ago. I had the same symptom you described. Glad it's fixed!
