The P1168, I got with an OBD reader from ADV AuTO, i decided to get a PEAKE BMW specific reader, and sure enough i got the correct codes which told me it was the pre and post Cat O2 sensors. I replaced both on the passenger side (it tells you which bank and number with the booklet and code reader) I reset and have not had any issues since.

Find another (competent) dealer. The codes are there to help diagnose a problem. Resetting them won't help, they need to find the root cause. You now know (with some degree of certainty) that it isn't the gas cap. All we can do is guess here, you need a technician who can follow it through and find the problem. Good luck.

i was looking at my sisters x5 and her gas cap is tight , no movment what so ever , mine moves up & down a little !!!! maybe thats the problem
also a while back i had the ses light turned off after i filled up with gas & the light stayed off for a good 450 miles but came on after i filled up again , another time i had it turned off & was on empty so i drove straight to the gas station which was about 5 miles away , filled up & it came on as soon as i turned the x5 on .

If the whole system is fully intact with absolutely no leaks whatsoever, then sometimes it is the DMTL module itself faulted...
