2002 1.8TQ Timing Belt

I just purchased a 2002 A4 1.8T Quattro with 29,500 miles on it. Factory warranty is still good through July 2006. I know about the coil pack issue (have a VW Jetta that was hit with that) and I know about the oil sludge. I've also heard/read many rumors on when to change the timing belt on this engine. Apparently, there are conflicting reccomendations on when to change it. Does anyone know when Audi is recommending the belt replacement, what other parts the service involves, and what the typical cost is? Thanks.

60k miles. I had one break on me at 70k...although it was a '98 model. But I believe all 1.8T's are the same.

they changed the 1.8T slightly in '01 and on

60k mostly city driving
80k mostly highway

if the cars over 6yrs old replace if it hasnt been
