Hello.First time Audi owner and Just purchased Ross Tech scannder per Forum members suggestion.
I have 2006 S4 Manual. 87000 miles
car seem fine at idle but when I drive it hesitates and drives very sluggish.
when RPM is raised to 2500 or over CEL flashes and sometimes CEL goes away soon as I slow down.
But sometimes it stays on solid.
CEL Code
P0300, P0301, P0302,P0305,P0307,P0308
P0174,P0172
so far repair shop replaced all the spark plugs, Coils packs, Injectors, fuel filters, Vapor Canister Purge Solenoid.
Car ran fine for for about 4000 miles then another CEL
P0300,P0301,P0302, P0303, and same condition as before..
errors appear under load not at idle.
At idle engine does not shake it is very smooth. It is very quite even at cold start.

Also Passenger side exhaust out put is very weak compare to the Drivers side.

Please Help.

What do the fuel trims look like? Any significant difference between the banks?

They are different.
I do not know how to post pictures so this is best I can do

I removed passenger side oxygen sensor before pre cat and sensor is tan color not black as I see the pictures of used oxygen sensor.
Is it normal ?

I would not call that difference significant. Moreover, those long-term numbers are all at idle, and IIRC, your problems come under load. Since you cleared fault codes recently, you're going to have to drive the car some before the "Partial Load" values will budge from zero.

Are these failed or incomplete meaning these failed or Incomplete parts need to be replaced?

No, it means the routines that monitor/test those systems have not had a chance to run (have not seen the correct conditions) since the last time you cleared fault codes.

Just drove the S4 for about 14 miles it started ok for few miles then on the freeway RPM does not go over 3000 very sluggish.
then CEL flashes as I was try to go little faster but soon as I let go the gas CEL goes away...
At lower speed when I raise the RPM pass 3000 I hear some kind of knocking sound.
Temp guage is set at about middle but engine bay seems very hot.
and Yellow Flat tire looking symbol has appeared on center screen.

These are the result of Log.

Wow, there's quite a difference now in fuel trims. Bank one went rich while bank 2 went lean.

Code:
09:05:30 Group 032: Lambda Control (Mixture Adaptation)
  0.4 %  Adaptation (Idle) Bank 1 Sensor 1
[B]  -9.4 %  Adaptation (Partial) Bank 1 Sensor 1[/B]
  -2.4 %  Adaptation (Idle) Bank 2 Sensor 1
 [B] 11.7 %  Adaptation (Partial) Bank 2 Sensor 1[/B]
I am not sure what would cause this, but hopeflly someone will have some ideas.

someone told me my S4 may have clogged cat. but I do not have any CEL for Clogged cat or oxygen sensor. what do you guys think?
it gets worse as temp goes up.

Remove before-CAT oxygen sensor and use a bore-scope "snake" camera to do a visual inspection? Those things are pretty cheap now; many will work with a smart-phone:

Removed Bank 1 cat (passenger side), It looks OK.
Do not see any broken pieces and I did shake the cat no rattling sound.
but as I mention before Bank 1 side exhaust is very weak compare to Driver side. Exhaust out put should be same on both side or is it normal to have ones side a lot more stronger than other side ?
I connected vacuum to Pre cat side of pipe and checked to see any air movements through the pipe.
it does move air but very of weak I am not sure how strong it should move air . Is there a better way to check if cat is clogged ?

I would also expect it to be close to equal, but I do not have a good mental (or any other kind of) picture of this exhaust system. Is it fully separate or are there one or more cross-overs or common paths?

Have the front pre-CAT Lambda sensors been changed? Most pre-CAT Lambda sensors are only good for about 50K-60K miles then they get sluggish.
You mention you have changed many parts on this engine but do not mention replacing these sensors.
Maybe one has been replaced previously and is working OK while the other is sluggish.
The car ignores these sensors until the engines has warmed-up so if it runs OK cold, this could be another pointer towards the Lambda sensors.

I also recommend performing a compression test on each cylinder. I have seen hairline cracks in the head cause similar issues once the engine gets hot.

Hello.
I managed to resolve the missfire issues.
car runs well now drive about 80 miles with no issues but now I have one fault code P0421 (expected since I have gutted pre cat bank1) It looked fine but it was at lest 90% clogged.
After gutted pre cat exhaust output was a lot more stronger. Now need install a new cat on bank1 now.
need to get a smog check but readiness is not ready after 80 miles of driving.
