P310B/012555 - Low Pressure Fuel regulation: Fuel Pressure Outside Specification


I've changed fuel filter , in tank pump to dw65 (wanted new couldn't find good used one) , has auto tech internals in hpfp , changed g410 and had new cam follower !

car goes flat around 4800rpm till 5800 ish then goes again could this be my hpfp dyeing ?

the auto tech was already fitted to the car when i bought it so don't no the age of it I've heard the solenoids can go faulty in the hpfp this correct ? any way i could check the auto tech piston for faults

any help or idea on what to log would be great i have full vcds so not a problem

thanks in advance scott

Now getting 000135 p0087-002 fuel rail/system pressure too low .

Not really sure what's goin on the car isn't happy past 5000rpm I have a 4 week old dw65 pump so surely that can't be the problem could it be the pump controller at fault I have a revision k thrust sensor but will fit another this weekend just Incase I've also fitted a fuel filter not long ago was the pressure recomemded the higher one can't remember what now think it was 6.6bar

Could this be
Fuel pump controller
Hpfp
Thrust sensor g410
