Hello I have a PUG 408 THP petrol (308 turbo saloon) . Recently he lit the injection fault light on the dashboard and accused the P0087 code. I checked with a scanner and the fuel line was just 6 Bar when it should be 50 Bar idling. I replaced the fuel filter but not resolved. But if I used the car for a few minutes power cycled again the pressure returned to normal (50-150 bar) and the turbo returned to work. That is, the high pressure pump is intermittent operation. This happens when the car gets a few hours off. Can it be regulator high flow pressure?Or even gas cap that you are not keeping pressure?
