In your case, since you know you have a good CPS AND the timing belt and internal cam timing chain have been moved (possibly incorrectly?)...I'd want to insure belt and chain timing is correct first.
If you don't have a Bentley manual (HIGHLY recommended as part of any tool box), your belt timing is checked with crank at TDC cylinder #5:

Crank here:

And cam alignment "keys" with large holes facing inwards ans all holes dead level...can check with straight edge:

But more accurately with the proper cam lock tool:
CamlockT40005.jpg?t=1302905759

If belt timing is correct, under the valve cover, the chain sprockets must line up like this at the same point (TDC #5):

Quick question, so after replacing the CPS Sensor with the new one nothing changed?

 

That's correct. No change.

And thanks for the help.

I'm just waiting on the cam lock bar to come in and I'll knock this out. Hopefully it's just the timing belt being off and I don't have to pull the valve cover off and mess with the cam.

Cheers

 

a missfire is when the cylender gets the fuel but doesnt get the spark to fire it back down.

 

oh ok, i havnt changed the CPS yet but i will sometime next week. You have a D3 right? If so have the dealer perform the recall on your coils as yet?

I'm currently in jamaica but when I get back next week and change the cps sensor ill update if it fix my problem

 

I actually have a 2.7 A6. Same principles though. And I didn't put a new sensor on, just swapped my roommates sensor from his car on mine. Luckily we drive the same car. And maybe try to find someone close by with your car and see if they'll let you borrow their sensor. It doesn't take more than 15 minutes from start to finish to swap everything out.

Good luck with your timing belt. Much easier than having to mess with buying new valve covers and everything else associated with that.

Cheers

 

Sorry for the late update I had some other stuff ive been taking care off. thanks for all the responses because they all help me solved my problems. The car had a full serice TB job done in Dec 2010 at Knops Audi in PA and it jumped time somehow it was a tooth off on bank 1 cam 1 which caused all the codes i was having which were :

18339 coolant fan J/293 malfunction p1931

cam position sensor G-40 not plausible-p0341

16884 random multiple missfire p0300

16685 cylinder 1 and 16687 cylinder 3 missfire

17538 fuel trim bank 2 to lean upper limit reach
p01130

18080 coolant fan control-1 p1672

17535 fuel trim bank 1 system too rich p1127 lower limit reached

16686 cylinder 2 missfire p0302

16814 catalyst bank 2

Knops Audi wanted me to tow the car back there for them to look at it which was understandable but i had left the car down in SC because i didnt want to drive it back and i was out of the country for a few weeks. The dealer was kind enough to go back in there and fix it for me for $580

 

Thanks for the update. Glad you got that sorted out.

Not too surprised to hear it was yet another dealer induced nightmare.

It's incredibly easy to get the timing right, if you just pay attention and follow instructions...BUT incredibly easy to get it wrong, if you're an incompetent boob with a piece of paper that says you aren't.

P.S. It is a physical impossibility for this engine, correctly serviced, to "jump time"...did NOT happen...I guarantee it! THEY screwed up.

If the same dealer corrected it, they screwed you AGAIN if they charged you to fix what they did wrong.

I'd be demanding compensation...and wouldn't shut up till I got it, esp if they didn't kiss me first
