A BMW 325i touring from 2008 came in with (high) fuel pressure error codes. The information from the engine management system was recorded and investigated. Low fuel pressure was OK, but high fuel pressure towards injectors showed a decreasing pressure while the fuel flow sensor was opened more. This could only mean the high pressure fuel pump was damaged. After changing the high pressure fuel pump (HPFP) the car responded how it should it be.
