Rolling marble sound under dash

[Shaun.Lovelock]

Not sure if anyone has experienced same situation, I’ve got a limited connect but have discovered a rolling marble ball sound from under the dashboard area, I thought it was coming from the middle removable panel on top of the dash but nothing loose under there, only place I can pin point is from the windscreen vent holes something has got in and now rolling in the space underneath I did manage to pick up a 10p coin from the windscreen vent on the driver side but I still have the noise I’ve tried exploring in the vent holes with my led telescopic camera but can’t really see anything unless I’m not looking in the right areas??

Turned out to be a roof felt nail stuck in the air vent by the windscreen I managed to pick it out with flexible magnet telescopic tool

Good result

Better than the time that I dismantled the whole dashboard in my car, to find the source of an irritating rattle, only to find the source was from under the bonnet

I was contemplating about stripping parts of the dash to find this annoying rattle lol, but the telescopic magnet tool saved the day
