I have this very annoying rattle in my A5 which I believe is coming from behind the radio or maybe behind the center air vents but it’s driving me nuts, it’s constantly there when driving about 10mph which is basically all the time.
Any help on what is causing it or how to fix it would be appreciated.
I have a video of the sound but I can’t post it here, I can send the video to anyone who thinks they could help.
Cheers

A rattle or a broken clicking/clipping sound? Does it go away when you turn the air temperature gauges up? As the device which control the atmospheric pressure (fan I think) with the inside of the cabin usually fails which is a pretty common fault, had it on my Audi S5 which would go away when I put the fan on full blast would only last about 40 seconds which was rather annoying but would go away
