I have reached 82,000+ miles now in my 2000 audi s4. I use a shell v-power fuel system cleaner whenever I get my oil changed. I was wondering what is the best engine resteror to help give them engine a little more life? Just your standard engine resterer 6 cylinder? Does audi offer a good product?

Unless you have some specific problem you want to fix, save your money and spend it on good motor oil. If you're concerned, you can do an oil analysis to find out how the engine is wearing. I think they're about $25, and they'll tell you stuff about how your motor is doing on the inside.
