Car Died, Pulled The Following Codes

Yesterday, while coming home from work, my car died while making a right hand turn. I pulled into the median and took notice of some error messages displayed on my nav screen. It had something to do with the fuel pump and then once I turned the car off, and restarted it, that message was replaced with one about increased emissions.

I was able to limp it home and pulled the following codes.

U0109 Lost Communication With Fuel Pump Control Module
P0192 Fuel Rail Pressure Sensor Low Input
U0109 again
P0192 again
P0301 Cylinder 1 Misfire Detected
P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0300 Random Misfire Detected

My thought process is that the FP control module went bad, making the pump lose pressure which started the misfires and put it into limp mode.

The car's got about 37k miles on it and is an '08 E92. I have not restarted the car, but I'm considering trying to limp it to BMW as it's not far from here.

I've done a search for the U0109 code and haven't found anything. Has anyone else had any experience with this?
