I have a whirring noise of sorts with moderate acceleration. It only happens roughly between 2-3.5K RPM. For example I'll start accelerating in 1st gear and I wont hear it until about 2500 rpm..then it stops by 3500 rpm. It'll change to 2nd gear and as it's climbing back up I hear it again at about 2500-3000 rpm and it stops again at around 4000 rpm. I made a little video long time ago and posted it on this thread. The dealer said they couldn't hear it. Although I can reproduce it every single time. Sometimes you just don't care enough to bother with it.
