Ok..... Use a 17mm wrench and turn the tensioner over until you can take the belt off the alternator.
Its the big silver square looking thingy not being too technical.

 

yah im a noob.... nooo clue what that is.... do u have a picture by any chance?

 

have you ever seen the front of an engine?? i think audi tech needs to be less mechanical

 

not really

 

Man i don't it shouldn't be too difficult though, just take a look at the front of the engine and look for the only "silver" thing on the belt drive with a square piece on top and use your 17mm wrench on it and turn it over one way, its spring loaded so its gonna take some pressure and effort.

Look at the second post (from brrman)

 

well... im bringing my car to get fix on the 16th.... i have a feeling my pockets are going to have massive holes...

going to get the timing belt done and the altenator fixed....

any estimate?

 

Somewhere around $1,000 if your gonna do the water pump too.

 

yah... he mentioned the water pump to.... he says that to fix the oil sludge he would have to get to the timing belt... so i figured might as well do it because it needs to be done...

the thing that i think is going to send my price through the roof is that he says he recommended to use the original audi tbelt kit....

he says most aftermarket kits arent to reliable...

so i figure if for a tbelt is like 300 max.... for an original its prob 600-700

 

The factory timing belt kit is the best way to go, but the timing belt has nothing to do with the oil sludge problem, he needs to suspend the engine and pull the oil pan off and change the oil pick up tube which isn't a cheap repair.
Plus a sludge repair is covered by audi of north america as long as you have all your oil change reciepts regardless of mileage.
