at what milege should i chage timing belt mineis at81k miles

There is no timing belt in this engine. It is a timing chain and Audi states it will last the life of the engine. I believe that is considered roughly 120k mi.

More important is that you change the timing chain tensioner. Get a good indy mechanic who knows this engine and they can tell you if the chain needs to be replaced when doing the tensioner.
