*Help please! Rattling/rolling sound on inside of driver's side A3 Sportback 2009*

Hi all,
Some MUCH needed advice please!

I have a 2009 A3 Sportback which, after leaving in my wife's capable hands for a few weeks, returned with what can only be described as the sound of a marble rolling around either in the door card area of underneath my steering wheel: This is especially prominent whenever I turn the car.

It really does sound like something has been left in a compartment that I don't know exists!

The question is... what compartments are there in the driver side of the facelift A3... I've looked and looked and can only see: the compartment next to the speaker on the driver's door and the small compartment on the right hand side of the steering wheel.

Thanks in advance!

Dan

Hi all,
Thanks for your swift replies! The problem was a rogue screw somebody had left in the cubby under the seat (thank you Neil C!) The question now is who put it there
