Hi this car runs food it only has codes012555, p310B low fuel pressure. At idle I have 4.88 bar 49% duty cycle at highway speed about 100 kms 3.6 bars and 80%
.I am ware of the updated pressure sensor but I fear it might have a worn cup, or camshaft. Does anyone have pressure specs for high side. thanks Mario

Its out of spec if you have a DTC or a bad sensor/bad wire-connection/ECU

I would of imagined you change the fuel filter already and that is a basic next to checking PSI and volume delivery.

Hi I changed the fuel filter and the pressure is higher now, I road tested rail pressure reached 100 bar but low pressure also runs higher 5.2 bar


This data is at idle, Thanks

I didn't check the parts catalog but most FSI engines use a 6.0 bar regulator type of fuel filter so that electric in-tank fuel pump may not be producing enough pressure. If the electric fuel pump duty cycle exceeds 70% that DTC may reoccur and checking the low-side volume and pressure (with a mechanical gauge) would be my next step.

I do not have any reason to believe that engine has cam/lifter/pump mechanical issues based on that fault code alone.

Edit, I forgot to include the link http://wiki.ross-tech.com/wiki/index.php/P310B/012555

I replaced the pump and the filter, The old pump had a very bad current pattern
