Hey guys, this is my first post to the forum and I'm looking to get some help. A little back story on the car: It is a 2007 A6 4.2 V8 that I bought a while ago for $2k because the guy thought it needed a headgasket, but I figured it was just intermediate cooling pipe o-rings (which it was). So I do know how to work on these cars, but this new problem has me stumped. It has 128k miles and runs perfectly aside from the idle.

The Problem:

I have a random code for the HP fuel sensor and one for the O2 sensor. They only pop up once a day on the first cold start when it gets to about 640rpm (see AutoScan)
And this thing idles like a cammed out 70's muscle car when warm at about 640rpm. when cold started it has misfires but the computer does not recognize any (checked adv. blocks in vcds and 0's across the board)

Things I have done:
Oil Flush and change 1k miles ago
Run injector cleaner
Performed the CRC Intake valve cleaning with the car running (not manual clean) Valves looked fine when I had the intake off but was planning to do a cleaning when it warms up again in the spring.
New PCV valve
New Coils
New Valvecover gaskets
Fixed all oil leaks

Things I question:
Intake runners are operated by two motors, but bank 2 is higher than bank 1 (misaligned?) ..Throttle body adjustment performed, didn't change anything.. There is a high pitched whining sound
from the actuator motor when the car is turned off. (almost like its stuck, but moves freely when revved)
Had an intermittent "Bank 1 catalyst Below efficiency" That went away about 6 months ago and hasn't come back (I've heard these cats go bad)
Runs up the RPM range perfectly with no misfires
Block 93 has all adjustments between -/+2 except for Bank 2 intake phase position that has no reading (Blank box).
I removed and regapped all of the spark plugs to 0.028 and it seems to have liked it just slightly more, but the spark plugs are AutoLite Platinum (from what I understand a sub-par spark plug)

So Just looking to see what would be next recommended as far as what to do, my thoughts were swapping the camshaft sensors to try and get a reading on bank 2 Intake position Phase and then probably inspect the catalytic converter.

AutoScan:

Ignore the electrical faults, that was due to a bad Sirius module That was draining the battery. ( battery was and is fully charged now)

Welcome to the VCDS forum OP and did you JPPSG yet?

https://forums.ross-tech.com/showth...essional-Problem-Solver-Guide-quot-JPPSG-quot



Maybe induced issue during repairs conducted?

VVVVVAT Time is it & for air leak repair/trace/HPP mechanical's for inadequate stroke/leak down, injectors being plugged/incorrect atom pattern or HPP or lift FP and to be un pimped to remove the FOD + enhance grounds?




So I do know how to work on these cars
You mean change parts on these cars right and to your knowledge correctly, maybe recheck work?

I live in the Northeast so my working has slowed a bit. Yes I understand what VCDS measurements and blocks mean and am pretty handy with Google. I've done a tear down to the block and rebuild of a 2.0T FSI and the car is 8k miles since with not a thing wrong with it, so yeah pretty embarrassed that this car is kicking my brain here. Since posting I have gone over all vacuum lines around the engine and smoke tested. On the coldest day so far at about 16 deg. F it had acted very funny with the throttle body but after doing a TB alignment it has gone and not returned. When doing output testing everything actuates. I have since messed with it more and reset trims and now my idle values are pretty even yet my partials are almost fixed opposite of each other. I have even exhaust pressure from each exhaust pipe so my next check will be blockage but don't think it will be that. Still rough idle. Funny thing is it is worst cold and hot but when it gets halfway warmed up it idles very smooth aside from a miss here and there that won't show on the misfire counter in VCDS. Then once warm it shakes at idle again. And I have swapped and cleaned all cam sensors and still have a blank value for bank 2 cam phase timing yet don't have chain slap and only have an intermittent miss on 5 when 4 acts up.

Could a weak HPFP on one bank only cause this? Or no because they connect? No codes still :(

Maybe it has something to do with the fuel PSI sensor & the OBD2 data should be considered to fix the fuel system by isolated mechanical testing to identify the failure?
