I have the above with god running but after warm up and idling it logs the above fault and runs rough with very poor acceleration.

When you examine the live data in the fuel pump module it shows desired fuel pump rpm as around 6500 but actual as 3000rpm. I have noticed on other similar cars these are matched ?

When looking in live data for engine control low pressure fuel is around 5.5 Bar but high pressure is 6.0 Bar.

Am i correct in assuming the high pressure is too low and this is causing the issue ??

What should the high fuel pressure be on these at idle as I cannot seem to find an data anywhere ?

Searched this forum and found the "tech note" about high pressure pumps and this covers my model but not engine !

Any help would be appreciated
