My mates S4

Hello everyone I swapped my golf for a 3.0tdi Quattro off my mate which is soo quick.
Anyway he had his fast Audi out which is total perfection but the passenger side air bag was making a squeaky racket, really annoying ,any ideas please ?

 

Most likely the glovebox or its contents, never heard of a squeeky airbag before!

 

Definitely squeaky rattle just under the passenger side air bag.
Next time I'll record it.
