Update on the SES light. Today I took the X3 to work, about 13 miles drive and about 7 days after the SES light came on. I requested an apointment for today, with the dealer, for the SES issue. I was supposed to have taken it afterwork. After I finished work, I got in the X3 turned the ignition key on and the light illuminated for 2 secs or so and then it turned off by itself. Apperently, it was definetly the refueling that some how tripped the system. And I guess the driving caused it to reset. Anyway peeps thanks to all for answering this thread. Specially JCL! You were right on the money, with regards to the most common SES indicator comming on issue. Hopefully, this helps out other bmw newbies, like me, in the future.

Thanks again!
