My gauge pods (the unit behind the steering wheel with the tach and speedo in it) rattle ridiculously whenever I go over bumps. However the rattling goes away if I push down on it, making me believe it's just a bit loose. Any ideas on how to tighten this up, or should I just get it done on warranty?

there's a Rattle Hunt thread by Polak that talks about this. I think someone figured out how to fix it...

as long as you're still under warranty, its all free.
