I have a 2010 Peugeot petrol 1.6 which faults P0087 and comes up depollution system faulty, To date I have replaced coil packs, plugs, High pressure fuel pump but still I have this fault. When cold the fuel rail pressure is showing 80 PSI which I believe this is where the fault lies but when you press the accelerator and give it some revs after about 20 seconds the psi raises to between 800 and 900 on idle and then the car runs perfect. Has anyone any advise please.
