Woah! hold your horses caballera- you got in deep just buying this complicated piece of Teutonic Trouble- don't make things worse by messing around under the hood when you don't know what you're doin'- the best course is to get rid of it, fast- but if you insist on keeping it, find a GOOD Audi mechanic- oh, please, just get rid of it-

lol jam. Audis are not so bad once you got a good mechanic. I do all the work on mine myself unless it requires a hoist. So what you need to know... Replacing the thermostat is a big job, it is often done during a timing belt change along side the water pump, pulleys and tenser. This at audi is a 1500$ job but at a skilled audi/vw specialist some where more in the ball park of 1000$. if you only just bought the car and have no idea how long ago the timing belt was changed i would recommend going back to the person you bought it from and ask. If they do not know just do the whole kit to save headache down the road. i would also have all the pvc checked for the crank case breathers. more often then not one of the pvc tubes disintigarates on the 3.0L engines and causes the car to stop running or idle badly.
