Hello Guys, I have some issues with damn resonance noise at about 2000-2300rpm on my Lupo 3L for some time...Exhaust looks to be fine externally at least, no leaks, no corrosion... What we found strange is that there is some air blowing OUT, the right side from the small hole in the air filter housing... I guess it should be sucking the air in, not out... Even more strengly, when we disconnected the upper part of the hose, it sucks the air in as it should? What do you think about this? 
Could you check how it is on your cars...? Cheers guys.
