Sorry for the long read in advance,
So to start with my 2011 f07 530D GT low pressure/electric fuel pump stripped its self out and long story short the particles from the pump made there way into the high pressure fuel pump and beyond, new EFP, new HPFP new Pressure Regulator, new pressure sensor and new injectors have now all been fitted as the originals were leaking, I’m now struggling to get any rail pressure, consistently that is. I got it to a point it would start on the key but I would get a drivetrain fault 248700 rail pressure too high, so this is where the new regulator was fitted in hopes it would fix it. Since fitting this I’m unable to get any rail pressure above 30-40bar. I’ve bled it for hours and had the battery continuously connected to another running motor. I feel like I’ve got a dodgy sensor/ valve. But I’m at my wits end with it and I can’t just keep unloading the parts cannon onto it. Sorry for the long read/rant. Additionally all injectors have been coded in and as adaptations have been reset. Thankyou in advance if anyone can help.
