[s-cars] Fuel Pump R&R urS6 avant - Update - Partial Success.....High RPM lean out still present

[Jim Fleischer]

Hey All,

Thanks for the help......got the new Bosch pump in and she starts, runs, has a bit better throttle response (I think) but the high RPM lean out condition persists.  It was the original pump, so good preventative maintenance, however, I want my kick in the pants power back!
I can hear the turbo whine, but it used to literally scream, and I mean SCREAM unusually loud, to the point that when I bought the car 80K miles ago, I thought something was wrong with it.  Now that is doesn't scream, I'm thinking something is wrong with it.  There is literally no back seat push above 4K RPM.  Power is very linear, like a NA engine (feels like the 7A in my old coupe! Depressing!).  Here's whats' been replaced so far....

Fuel Pump, Fuel Filter, O2 Sensor, Fuel Pressure Regulator, CPS, cleaned the MAF properly. Plugs are NGK's that Dave Dawson recommends and have about 7K on them.  May swap them out anyway.  Could it be the wastegate diaphragm?  Fricken coils? POS? I think I've addressed all the fuel components, maybe not the relay.  Any other thoughts?

Just pulled codes......2222    ECU Internal Pressure Sensor       I think I'm F*cked........

Thanks again as always.....

  DaveF and I have differing views on this, I think he's laughably moronic to go in via the 3rd row.   He thinks I'm so stupid as to be a hazard to myself and others for wanting to go in from the 'front' (aka climb in a rear door with the seats folded, remove the (5?) semi-hidden screws that hold the carpet to the back of the seats, then take out the cargo loop on either side.   But srsly both work fine. 

  Either way once the carpet is up it's all just as you see in most online pics except Avant is way significantly better than the crawl-in-and-suffocate sedan access.  I of course I do keep both doors open as well as the hatch to keep good fresh air flowing through, and that way not as much cigarette smoke gets in my eyes as much while I'm working.

      Jim, 

      The Fuel Pump access cover is located between the third row seats and the second row seats. You can either pull up the carpet from the back of the fold down second row seats or from the carpet that dives down under the third row seats (that's where I have accessed it). You may need to remove a couple of fasteners for the 3rd row seat belts to get the looped holes in the carpet out (when you see it you will know). The access panel is the black circular thing in the photos you've probably seen already. 

      Good Luck.

        Hey guys, 

        I'm replacing the fuel pump in my avant today (hopefully!) and found a good writeup on Quattroworld by Dave F.  (Thanks Dave!)  Just a couple questions, as this is my daily driver and can't afford to screw this up today! 

        First off, where is the pump on the avant?  Figured I'd pinpoint it before I started taking up carpet haphazardly.  My car has the third row seat if that matters. 

        I replaced the fuel filter a couple months ago....it is recommended to replace the filter when replacing the pump.  Do I really need to at this point since it was replaced so recently? (It would take me out of the game today unfortunately.) 

        Are there any specific tools needed? 

        Any helpful BTDT's?  Encouragements welcome..... 

        The tank is drained about as far as I can without getting stuck on the side of the road and I have the afternoon off......thanks for the help fellas! 

        Best regards,
