Read the Audi/VW forums. The horror stories are non stop and the bills are astronomical. Both the V6 and V8 engines with the multiple chains at the back of the engines destroy their plastic guide rails and the only solution is to pull the engine in order to gain access. At this age its cheaper to simply replace the whole engine with a used one.
The parts list alone on this type of repair should be enough to give you pause.
