Hard start after refueling

Hi everybody, new here.
I have an 07 750i which turns over a few times before starting after every refuel. My check engine light came on and stayed on. The dealer told me it might be the fuel cap and to make sure it was on good and wait a few days to see if the engine light would go off on its own. It didn't and i took it in and they told me it was a bad DTML pump. I had it fixed and a few weeks later the car rough starts after fill up and the light comes back on. I did get the fuel cap error briefly before the engine light came back on. This happen to anyone else?

Thanks

BTW I use Shell premium.

change the cap just in case.

I had the fuel tank breather valve go bad on mine - but it was also throwing a code. In my case, I experienced hard starts especially immediately after refueling the vehicle. Check codes. There's a DIY here: http://www.www.bimmerfest.com/forums...d.php?t=555805

Thanks! Will check it out.
