I've been searching for about 30min on what are the symptoms of a failing timing belt. What should I look for to know that my belt is on its way out, or is already gone?

How many miles do you have? What year model?
You shouldn't wait for symptoms of a failed timing belt, but should instead have it changed out along with t-stat, water pump, tensioner, and accessory belts between 75-90k miles.
From what I've heard if the timing belt breaks or craps out in the car, it won't drive. Audi designed it this way to minimize damage to the engine.

It's a 2001 A6 2.7T with 64k on it. I just wanted to know what I should look for to know that the belt is broken (IE: sounds, feel of the car, etc..)

My understanding is you won't feel or hear anything. When it fails it's sudden and you'll know because the motor will de dead and you'll find yourself stranded.
You're probably good for another 25 - 36k miles.

If the belt breaks the engine will never run again without 3-5,000.00 of engine work *. The sound it makes when the belt breaks, is clink clink clink as all your valves are bending. The sound the belt makes when it is wearing out...silence. There are pulleys that can squeak before they fail, but really it is a job you just get done when it needs to be done.
* sometimes miracles happen, it did on our Toyota truck, the belt broke while starting the truck and did no engine damage.

"There is not way to see the belt with out taking half the front of the engine apart" Is this true? Please excuse my butting in to someone elses post, but:
My 2.7t w/ 80k is at the dealer for the 80k service today. The dealer just called to recomend that they do the timing belt be changed cuase they can see that it is cracked. Can you see to timming belt from a valve cover or some other access point at the top without pulling the bumper etc.
thanks,

I think the stealer is bs'ing you. On my 2.8 you can't see it at all because it has multiple plastic covers protecting in and those covers are behind the accessory belts. Removal of the front end is required.

I just had mine replaced at 72,000. Highly suggest you get it done sooner than later. You will regret it if you do.

Thanks for posting those pictures. That totally rocks.
So I checked the service manual after picking up the car today, and my timming belt had been changed at 61,850, with the water pump and thermo. I am so glad the previous owner had the records. I imagine the dealer just saw 80k and wanted to cover thier ass by recomending it.... I'll give them the benifit of the doubt.
So it looks like the radiator and stuff pivot out of the way but stay attached to allow access to the engine!? cool. Thanks again, pictures = a thousand words.
cheers all,
Its funny, my old volvo 240 has a "non-interference" engine - when/if the timming belt breaks, the valves do not colide with the tops of the cylinder heads. Nothing happens except the engine shuts off and you get stranded. Makes you wish all cars were that way. But then that thing is slow as hell.
