I'm get P310b fuel pressure regulation fuel pressure outside specifications

Question

Hello everyone, please help
I'm get P310b fuel pressure regulation fuel pressure outside specifications for 2005 Volkswagen Golf 5 FSI 1.6 blf, the car idle on low pitch and it lose power during acceleration,
I tried changing fuel pump and high pressure pump, the problem still there

Any help is much appreciated

Answer 1

The P310B indicates that the Fuel Pressure Regulator is out of specification. Since changing the Fuel Pump did not resolve the problem, the Fuel Pressure Regulator must be replaced to repair the problem. The Fuel Pressure Regulator is under and to the right of the intake manifold.
