9-3 Noob, convertible rear end noise
 

Hello all,

My second noob query of the day. My newly acquired 2011 9-3 convertible is fun with the roof down, but when I have the roof up there is rather a lot of rattle from the rear, especially over bumps. Is this just the space in the trunk where the roof goes bouncing and rattling. Or is it something I should get looked at. I looked at the brakes and nothing seems to move on them. I looked at the license plates and they are not set up so as they can bounce against the body work. Convertible owners - does your vehicle make odd noises from the trunk/rear when you go over bumps with the roof up?

Thanks
- Mitch
