Citroen documentation said: Regulation of the fuel pressure in the rail : Pressure too low.
The engine start normal, everything looks normal, but I noticed lack of power around 3000 rpm and can not go above.
This show up when I change fuel filter.
After this I put back the old fuel filter and everything became normal, I clear the code on ECU and after few drivings that code did not show up again.
Is it possible that the new fuel filter can do that fault code, or might be a problem in the fuel valve on the pipe line to the tank?
the valve is shown on the attached picture No.10.

Any one how can help with this code, or to locate where is the problem?

I did not mention that in ECU I have fault code P1351 but I think that code is not connected with P0087.

Hi goran, if the car was ok with the original fuel filter, it had a problem with the new fuel filter and the problems disappeared with the old fuel filter, then I would say you have a fault in your new fuel filter. Maybe its a fake, or badly made, but it does sound like the fuel filter is a problem.

If the fault is with the original part 10 it would be present all the time that original part 10 is present and would only be cleared when that part is changed or replaced. Did you change that part number 10?

I think they are unrelated too.

thank you for reply,
I did not try to change the part No.10 - the valve, but I did not mention that when you blow in to the new and old fuel filter I noticed different resistance, the old one (original) has bigger resistance then new one. For me is not logical that lower resistance to have influence to the fuel pressure, because during the exploitation of the filter is normal get clogged and get more resistant and to decrease the fuel flow.
From the other hand, maybe the new one is bad, but I bought from Citroen dealer and look same as old one.
Is it possible to have problem with fuel pump in the thank or some where else?

So if you can remove and recreate the fault by removing and refitting the filter and not changing any other parts, you can be sure there is a problem with the part that brings the fault, which is the filter.

What happens when you fit the new filter again?

Its worth priming a new filter with clean diesel before fitting and checking all the correct knock-outs are removed before fitting any parts to the filter (some filters have pre heaters and water sensors that need to be fitted).
