    Default P0087: Fuel Rail/System Pressure- Too Low

    Good morning,
    Does anyone know what the most common cause of this issue is on a 2013 Peugeot 508 1.6 THP. There doesn't appear to be any obvious fuel leaks visually or can I smell any. It is mostly on a cold start. I clear the trouble code after warming up then it drives normally but can be a bit touchy.
    Thanks in advance for any assistance.

    I'm no expert but sounds like a fuel pump on its way out or could be the fuel pressure regulator.

    Probably the best form of diagnosis is to get the fuel pressure tested and see if it is in spec.

    Most common fault is the HPFP (high pressure fuel pump) on the engine, or the lift pump in the tank.

    If it's only on a cold start, it could simply mean your battery is failing.
