In spirited driving it has happened 3 times over a period of a month or so...I have heard what sounds like gas escaping...blow off valve type noise...I am stock, but I also have not noticed any power loss when driving...do I have a leak or is this normal? or are my bypass valves leaking or the infamous TBB...

Thanks

S4...sad to say...stock

ie it's not just happening when you're lifting off the throttle? if so that's normal (duh, just had to make sure you knew this.)

if it's happening when you're accellerating, then it's very possible your DV or TBB is leaking *shrugs*... i'll leave an actual S4 owner to give the final word on this

(i'm just REALLY bored at work and trying to kill time right now )

it's OK... just the diverter valve doing it's job
