Guys I really need some help. I am driving from Boston to Denver and ran into some issue with my X5. I drove last night from Boston to a town outside of Albany. Since this trio is 2k in miles, I decided to get the oil change. I went and bought the oil and stopped by Jiffy Lube to have them change my oil. Probably should have went somewhere else but they were the only one open. I notice maybe about 15 minutes into driving that I was having some misfire, but thought it was the radio.
Fast Forward to driving now and I get a CEL and get low fuel pressure sensor. Here are all of the codes:

Based on the codes above I went and bought a new fuel pump and replaced that. Still have the same codes. I now think that maybe a fuel pressure sensor is unplugged or something. Can some tell me where the fuel pressure sensor are.located.
I have a 2014 BMW with the n63 4.4 engine. I am trying to get home because my girlfriend is having surgery on Tuesday. I could wait until Monday when the BMW shops open but I wouldn't make it to Denver for her surgery. Just really need some help. I am good with tools it is just this has me stumped.
Are there any sensors near the oil filter housing that maybe they disconnected that would cause these?

High pressure fuel sensor on the rail?

whonneb - I'm not much help at all on the 2014's but if you are waiting until tomorrow to get it checked...
out of warranty I would see no one else but John or Jeff Negus at Larchmere Imports. By far the best indy in the area.
