hi I have a weird rattle/wind noise a bit like leaves rattling at high speed coming from the near side air vent area, can any one help?

Something has found its way into the ducting. Do you keep the scuttle plate at the base of the windscreen clear. I had small bits of debris find their way into the ducting some years ago but they eventually cleared. 405 AB exec seats Baltic and Cirrus

hi I have not had the car very long, but will check this. How can I gain access into the ducting to take a look?

+1 with above but also, if it's a buzzing sound, it could be a loose rubber seal at the base of the windscreen which resonates at speed. I've got it after a new windscreen was fitted a few weeks ago. I'm getting the dealer, who fitted the windscreen, to take a look next week. 2012 5.0L S/C

thanks for the help. I think ive sorted out the problem subject to a road test, the black plastic side windscreen trim was loose.
