RE: Blow off valve
Ok, how is possible for me to not laugh at this. I'm splitting down the side. Oh yea.... he was joking about that ebay thing, do not get it. And how old are you man. New B7, damnn... thas hot. Do a search before posting a question. If your asking it, odds are someone before you asked it.

RE: Blow off valve
Sounds like your on the right path... anything performance oriented in mind?? The thing with Audi's is you always have to keep the waranty in the back of your mind. If your going to do anything to it make sure you can "not let the dealership know you did it". Any more pics of it?? A night shot would be cool with the lights.

The Audi turbo system is a closed loop system by which all unused boost that is spooled during off throttle and gear shifts must be re-routed within the system; it cannot be vented to the atmosphere due to the dependence on the MAF and ECU to properly read and interpret air flow dynamics within the intake tract. Therefore BOV's (Blow-Off Valves) are not used because they create a rich air/fuel condition (i.e. less air to fuel ratio) which will damage the catalytic converter, create soot on the exhaust pipes, and cause occasional misfiring (due to the purged air) which will result in ECU miscalculated timing adjustments and other errors.
For Audi closed loop turbo systems, a BPV (By-Pass Valve) or DV (Diverter Valve) is needed to recirculate the purged air and keep it within the intake tract.
