Hi all. i was out for a drive the other day in my 2002 A6 2.7t. All was going normally. I switched the car off for about 20 minutes and when I pulled away the car had no power, running really flat. There were no noises, warning lights or anything, just running totally flat!! My guess is the recirc's so ordered a new pair just in case. Any other ideas? I'll get it connected to VAG-COM and see what else there is.
Lots of places for those to leak boost. Vagcom is likely to say boost threshold exceeded, mine was a huge split at the throttle body boot. I ended up buying a complete silicon hose kit.
