Persian_535i

Had a friend come over today with a device that reads error messages through the OBDII port and I had 5 messages show up on his device to my shock. Not sure what they mean since I don't have a guide for error codes but I found something for the 3 series so figure it might be similar.
U1126
U112V
U1101
P1408
P1407

The 3 series codes I found (only ones I could find said this)
U1126 DSC error message
U112V Couldn't find this one
U1101 Lost communication with ambient temperature/Relative Time
P1408 Fuel Level Signal 2
P1407 Fuel Level Signal 1

Maybe it is totally off, but anyone know what any of these codes mean? My vehicle is a 2008 535i btw...
