Just had a call from garage i took it to they havent a clue wahts up with it all they can tell me is its loosing fuel pressure when it comes on boost rather than increasing it so not sure what that relats to?
Have you changed the fpr? I haven't read back through all the post so apologies if youve ruled it out. I'd also be checking the fuel pump (check voltage under boost), filters and everything else associated with it.
It might we worth checking your injectors and seals Chris, I was losing boost through mine because the fuel rail was lose. Only did it under heavy boost, the injector was being pushed out by the pressure. Stank of fuel after i'd give it some.
The FPR has been changed a couple of times between 3 and 4 bar so same on both dont think its that.
You know what block it is to log fuel pump as can give that a go?
not notices any fuel smell but maybe give it a try how do you get them out and check them you know?
gonna go get a new fuel filter and swap that to rule ti out dont think there much anyway are they.
So FPR,Fuel Pump,Fuel Filter,Fuel Relay?
I did say to you last night it COULD be you injectors..
The O-rings aint Expensive for the Dealers...But just look in to it abit more...
U swapped ur fuel filter yet?

the o rings (from dealers) come to about £18 for the 8 -
if your going to change them there are a few hidden bolts holding the fuel rail down -

does anyone know what block to log to check the fuel pump then just been looking though and cant see to find it.
Does anyone know if the fuel pump is inside the fuel tank or outside?
Also anyone know how much one would be roughly, spoke to a mate that thinks it might be that.

In most cases the fuel pump is under the rear Seat bench under carpet a big plate circle thing...
you cant miss it

Pump is in tank and under the rear seats. Would be surprised if it was your pump. Think they come in around £120.
Also if your pump wasnt supplying enough fuel then when you changed ecus it would not have run fine and it would be a constant fault.
What if there putting to much fuel in would that be pump or injectors?
Cause i think its putting to much fuel in but not enough fuel pressure if thats possible?
Is there a way of logging the fuel pump on vag-com?

The fpr limits the amount of fuel that goes through it to the injectors. If it is overfuelling then the pump will be working fine and it is either your fpr or injectors.
well it does same with a 3 bar fpr so must be injectors then could be blocked or just faulty all together. but have to see if can get each 1 or just swap all the lot there expensive though aint they?
