Hello,
I get the p0087 code on cold start (after about a min of ideling), car starts studdering (revs dial rotates 100-200 revs up/down) ... High pressure petrol value in this case is low (obd measure). If i shut down and restart car comes back and high pressure stables at around 50bar on idle.
So...am i doomed = faulty high pressure fuel pump? (Very expensive as we know..)
Thx

There is a (slim) chance that it might be the in-tank pump failing. You would need to put a gauge on the test port near the top engine mount.

No, the fuel line from the tank has a connection and Schrader valve near the top engine mount (at least that's where it is on a 308). From memory, the pressure from the tank pump should be 5 bar. There is no sensor on this line, so an external gauge is required. Maybe you see this pressure at the high pressure sensor before starting the engine.

Before starting the engine there is indeed a pressure of 4-5 at the high pressure value

Replace the filter with a different one. Recently someone had the same problem with a supposedly new original filter on. After putting the replacement on, the problem went away.

@xantia_v6 is there a way to get a hold of the technician's manuel explaining how to replace the fuel pressure sensor in this thp engine? It is buried so deep that i guess there might be some "trick" to ease the process...thx

Re: P0087 1.6 thp 156bhp (Peugeot 508)
As far as know, there is no official procedure to remove that sensor (alone), as it is supplied as part of the fuel rail. I believe that separate replacements are available from after-market sources.
I have not removed that sensor or fuel rail from my car, as removal of the fuel rail (officially) requires replacement of the injector seals which requires special tools for sizing the seals, and the teflon seals are expensive.
My experience is with the Peugeot 308 where access is also tight (don't know if the 508 is different). With the inlet manifold removed form the head and pushed back, there is probably just enough room to access the sensor, but it would be very awkward. Access from below may be possible with the link section of the exhaust pipe removed, but there is only space to get one hand up through the gap, so it is not much fun either.
In your predicament, I think that I would be trying a replacement high pressure pump, as it is much easier to fit... if expensive.

Thx, this is how it looks in mine... ...
Well, there go 500$ (before taxes and shipping...)
