P2293 - Fuel Regulator/Pressure To Low
P0087 - Fuel Rail/Fuel Pressure Too Low
Already done:
New HPFP (OEM).
New fuel pressure regulator on HPFP (G410).
New fuel rail pressure sensor (orange one).
New Fuel filter (OEM).
New Cam Follower cam shaft shows little of wear.
Fuel rail pressure isn’t getting above 7 bar for whatever reason.
Mechanical gauge shows 80PSI (5.5 bar) when hooked to a shredder valve on HPFP, and when hooked in line before HPFP shows 50 PSI (3.4 bar).
Measuring blocks 103.1 shows 6.5 bar. When the engine is off for some reason the rail pressure is climbing up to 121 bar in approximately 10 mins.
As soon as i start the car the rail pressure dropped down to 7 bar and no change no mater of the engine rpm.
