I think first step in fixing a car is to check for any fault codes. Could also be a bad HPFP too I guess.

As for reading your injectors... I think you have to pull the plastic cover over the valve cover and physically read the bar codes on EACH injector. I don't know if you can read the injector serial number via BMW's code reader. ?
I'm taking it in tomorrow to read faults. I owned my car since new the HPFP was replaced twice, and have had that LPFP sound when I unlock for a long time since the second replacement. I have no long cranks, car starts immediately. Will check tomorrow what they come up with and ask about intake cleaning.
