Do you(or the OP) have the new-er SW update that runs the low pressure fuel pump(LPFP) when you unlock the car door. ?

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. ?
