Just recently bought my 2012 A4 and i put just a filter in it about a week ago, i here the turbo spool pretty good but theres another noise that seems that air is sucking in from somewhere else through the filter, i checked if the seal was tight & it was but it kept doing it. And every time i would get on it i wouldn't really go anywhere before, all i here is just a weird noise. Just wanna know what i could do to solve this problem.
