Fuel pressure problems
Uncleben:
Well, I fitted the new HPFP today.................and it seems to have fixed the issue! couldn't drive it too much as the mot has ran out but gave it a couple of full throttle runs in 2nd and 3rd and it pulled strong and clean, so looking promising.
Wasn't looking forward to doing it as i'd read so much about the banjo bolt, but with a flexi head 10mm ratchet spanner and long m8 triple square bit it was a doddle, had the old one off and new one on in 30 mins, only trouble i had was where the schraeder valve should be, someone had replaced it with a cut down 13mm bolt, completely different thread, so didnt fancy forcing that into my new pump! luckily still had the old low fuel pressure sensor, so screwed that in temporarily until i get the correct part.
The cam follower looked fine so re used that.
Many thanks for all your help, especially @Pudding :happy2:

Hello, was the problem solved????
None of these topics have an answer on how the problem with P1063 was solved.
Uncleben:
Well the hpfp fixed all my issues, car ran fine for another 7k miles, sold it 2 weeks ago as sills were rotten amongst other issues!
If you are experiencing similar symptoms to mine then give the hpfp a try
Kaarters:
I tried with another working pump without any change still same issues.
Got only P1063 fault code no check engine light which is strange.
I can't go above 3000 rpm.(kind of limp mode)
Live data showing:
Rail pressure 6 bar (lower side)
Target value 50 bar and actual only 6.4 bar (high pressure side)
Tried another pump, sensor, replaced filter nothing helps. What voltage should be in the pressure regulator connector??? It shows me 4.5 v but according to some sources on the internet it should be 12v. Maybe you remember when you worked on your car what voltage was shown to you in the two-pin connector above the high pressure pump???
Running out of ideas 😞
