It makes as much sense as a 10 foot Wookie on planet Endor.Make sense?

Like Jack said above, this is an electrical fault so we need to take that approach when attempting to fix this vehicle.Hi, I am diagnose a fuel pressure problem in 2009 3.6L Gas Audi Q7.
I would like Ross Tech help with a couple things please...going back to the beginning of this thread on how to diagnose the problem.
- how to measure 1. lift pump PSI and volume.
The fault code actually refers to the N290-Fuel Metering Valve , for the BHK engine. So look for this when using the factory wiring diagrams.008852 - Fuel Pressure Regulator Valve (N276)
P2294 - 004 - Open Circuit - Intermittent - MIL ON
How do I do that with the VCDS? (This is what Jack said to check first.) - what Block/Group to see what pressure in Bar the HPFP is putting out?
Is there a way to be absolutely sure what is causing this problem? I have read that sometimes the HPFP needs to be completely replaced as does the cam follower.
But I am reluctant to do that without a certain diagnosis, since it will be over $1000 to do.
I have seen this in 2.0 T cars and High pressure Pump was bad.
As DrPeter suggested , check MBV 231
This pump do not have follower, it is new design with roller.Correct Marin....
The regulator is part of the HP pump and normally not a spare part....... it is absolutely possible.
However, I have seen more issues with a cam ramp or follower causing a flutter resonance, this excessive vibration creates an electrical disruption to the N290/N276.
Your pressure is way to low, I can bet this is bad pump problem.Hi Jetta.97, here is the screenshot of MVB 231. It looks like not all the readings are showing that are supposed to.
The engine was running at this time at idle. Field 3 says Test OFF.
I have also included MVB 103 and 141. See on 141 Field 1 and 2 are at 0 Bar.
Does this diagnose the problem as a broken HPFP or more electrical troubleshooting?
FYI Marin:This pump do not have follower, it is new design with roller.
