Keep in mind that tensioner assembly is the same that will be in any 06 to 08 GTI or Jetta with the FSI 2.0t engine (same exact engine).
And VW dealers can sometimes be a bit better on price since the Audi dealer seems to think they sell Ferrari's or something lol.

It will more than likely be the tensioner unless the belt is very dry but regardless you should change both.

This fix is very simple
There will be three 13mm bolts holding the tensioner to the engine (green arrows, keep in mind there is a 3rd one not visible in the pic)

Take a wrench (should be about 17mm) and put it on the bump on top (Blue arrow) and pull the wrench toward the radiator to twist the tensioner so that the hole in the front of it (left side red arrow) alligns with the hole in the rear half of the housing (right side red arrow) you will need a drill bit or something to put into the hole to pin the tensioner in place.

The belt will now be loose. remove the belt and then the 3 13mm bolts holding the tensioner... Assembly is exactly the opposite

How new is the belt? Did your noise start when the belt was replaced? Chances are your belt is either stretched or was the wrong one to start with.

Stay away from that belt dressing crap and mist a little water from a spray bottle or even spray a little WD-40 on the belt while it's making the noise. If it stops, then you know it's the belt and not the tensioner.

If you do replace the belt, go with a brand name. Gates, Dayco or Goodyear all make a good product. Stay away from discount store brands. You'll be right back where you are now.

Or you may have just gotten a little chili on the belt. (sorry,couldn't resist)

sorry i was not paying attention when i finished the first post. i realized that the belt is not new, its about 40,000 miles old already, or about 1.5 years old. (time flies)

Sickness, i'm gonna do what you said and change out the belt myself. if that doesn't work, then i'm gonna change the tensioner.

i'm also gonna call the vw dealership and if they can get me a better price on labor...and i called rod east vw and they said they don't service audi's...aaaand i got hung up on. now i remember why i didn't buy from rod east in the first place...got bad sales service...now bad service service

Well yeah the Audi dealer wont generally work on VW's and vice versa. I was just saying for the tensioner itself they may charge a bit less for it at the part counter, than the Audi dealer.

The part number for that tensioner assy is 06F 903 315

so i idled my car before turning it off in the drive way today and there was a rattling sound coming from the area of the tensioner.

after the car warms up it doesn't squeak anymore. but when i'm idling i can hear a faint rattling sound, so i popped the hood and found it was coming from the area of the tensioner.

The squeaking is usually the bearing in the tensioner roller. They calm down a bit when the bearing warms up (what little grease is left in there thins out) . But the rattling noise is usually the tensioner spring being weak. you will see the arm fluttering real bad

yup, sounds perfectly right, the tensioner moves back and forth with the oscillating squeak, and when i got home the tensioner was moving consistently with the rattling sound.

excellent, i've mulled over tons of forums for the past 6 months to see what the problem could be. when i finally decided to look take a picture and ask, my problem was solved in less than a day.

thank you guys, and thank you VWSickness!
