    Diagnosing fuel pressure problem in Audi Q7 - P2294 code

    Hi, I am diagnose a fuel pressure problem in 2009 3.6L Gas Audi Q7.

    The car starts and runs but has a lot less power than normal. and the P2294 code triggers the check engine light.
    Occasionally I also get codes that show random misfires in the cylinders.

    I have run the car with the VCDS connected and in the Engine section looked at Groups 103, 140 and 141.
    Below is a link to a screenshot with the car running:

    http://imgur.com/J62lg6o

    My understanding is that the spec for the high pressure is between 25 bar and over 100 bar.
    On my car it varies between 6.4 and 6.9 bar, but never goes higher than that. The first 2 fields in Group 141 are at a value of 0.
    I have replaced both the fuel sensor on the fuel rail (high pressure) and also the fuel sensor near the firewall and above the HPFP (low pressure).

    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.

    Please post a complete auto-scan........
    I would measure lift pump PSI and volume first seeing that it is properly regulated.

    Visual inspection of HPP cam follower is always advised and costs time to inspect which is cheap.

    (N276)

    Now this is an open circuit and I would trace the tracks with WD back to controller......Inspect wiring and connector at N 276

    FYI These regulator valves fail frequently.........

    I agree with Jack here but do make sure that N276 (or N290 in a wiring diagram) isn't getting power from a relay that could be malfunctioning or a spliced connection in the harness. I'm not in a diagram for this vehicle at the moment but most HPFPs are powered by a J757 relay.

    Thank you Jack and Dana for your posts! I am determined to figure this out (famous last words).

    Jack,
    The wiring is all new looking and wrapped, but I will re-inspect it.
    When you say the regulator valves fail regularly do you mean the High Pressure Fuel Pump or a replaceable component of this?

    Dana,
    Where can I find the J757 relay though on the Q7, any way to help me with that on the WD for this 2009 Q7?

    Also, I noticed these faults in the Auto-Scan, do they help us troubleshoot?

    Most importantly see how the auto-scan displayed this information changing your diagnostic path to take now verse PSI bullshit?

    Correct Dana N290 if looking at WD because no N276 exists I see in there.
    Looks like maybe Typo maybe in VCDS for BHK or typo in WD.

    Looks like D117 to D112 from stargate Track 131/194 splits to Fuse S13 15 amp which must be inspected!
    Through aforementioned fuse to stargate 166/196 track to D108 via J757 ( 2/87 )

    Now the split aforementioned should also be investigated for stargate 192/192 to V144 Fuel diagnostic pump.

    Now for the CURVE ball!!!!!!!!!!
    ......at fuse S14 via D108 goes to stargate 168/168 and is connected to ( OXS ) Oxygen sensor heater circuits.

    It is possible to get a flaky bad OXS heater .............that doesn't blow fuse but causes a disruption to power as brown out for N290 or N276.........

    Hi Jack, thanks again!
    Do I need access to the WD to follow your suggestions, if so is there a site online I can look?

    I have just now inspected all 4 15A fuses under the plastic cover drivers side firewall area. All these are fine.
    See picture what I am referring to:

    http://imgur.com/gRjf1sm

    Is one of these relays for the HPFP, or do I need to go into the area to the right and unscrew those torx bolts to find it?
    Also is there a way to test the right relay?

    How can I check or test the OXS heater (curve ball you mentioned)...

    You can go to Erwin.

    In USA : www.erwin.audiusa.com
    World : www.erwin.audi.com

    Dude you need to learn to test stuff not just swap parts and take a class.....You must RTFB.
    You could, however, unplug the OXS sensors heaters by plug or extract the lead just for them, using WD to see if the N276 DTC goes bye bye.

    Thanks but I don't have Erwin or the Fine Book or the Bentley. Guess I will see how much the subscriptions are.
    Not sure I understand your suggestion on the OXS sensor heaters, can you help with a little more handholding...
    I tried to remove the fuel pump relay labeled 614 but there must be a trick to that. Pushing the tab isn't working.
    Striking out on most everything. Your help is much appreciated.
