Quick qestions about the timing belt.
Just got off the phone with a guy that has a 00 1.8QT avant for sale with 78,xxx on the odo.
I asked if the timing belt had been changed out on it and he said it didn't need to be done til 105k. I then disagreed and told him in needed to be swapped out at 60k. Where then he disagreed...
Is there anything that i can print out and take to him when i go and look at it to show in fact it really does need to be changed out sooner. Or is it just one of those 'needs to be done' kind of things?
TIA

Oh and you might also want to ask what oil/filter he has been using
I'm betting he has been going to "my mechanic" for some time now and may be using junk oil and crapola oil filters.

call dealer, ask for their recommended service intervals...
I believe, they recommend 75.
it's not inexpensive to do so you should just discount the price from sale price.
in a perfect world, of course

See, what most people fail to realize is, it's not the BELT that is the problem...
it's all of the metal bits that keep the belt true to it's path, which eventually wear out, causing the belt to deviate from it's path enough that it becomes loose, causing it to skip teeth and introduce valves to pistons in a sort of mating ritual.
Alternative failure methods include pulley bearings failing (this includes the coolant pump on the V6 and later 1.8t engines), causing the pulley to seize, resulting in the timing belt dragging over the now motionless pulley, which wears the belt to nothing in short order.
Also common is the tensioner failing in various ways, either the tensioner loses it's charge, and goes limp, or in the case of the 1.8t, the little rod comes off of the lever on the tensioner pulley, and the thing goes limp.
The end result is the same for all modes, however.

like Kris said its the tensioner that seems to fail. My belt looked barely used at 60K
when it was replaced but if you look in the FAQ there are some pictures by carson when he worked a tbelt failured audi. so if you want to be on the safe side then change it soon, it not well good luck. Age of the tensioner could also be a factor since there were 2 people with milage below 60K but had some years on the tensioner that experienced a tbelt failure as well. the parts are 300$ and it can be done by yourself with some tools. thats cheaper than a new head
