Volvo Repair: C70 Noise, maria maria, type car

Question
I own a 2006 C70 and from time to time I hear a noise that sound like something is rattling in the dashboard. At sometimes it’s very load and others you can’t hear it.  I brought it over to the dealership a number of times but can’t find anything wrong with it.  Do you have any idea on what it might be?

Thanks,
Maria  

Answer
Maria, Since the car is under warranty, its their responsibility to repair the car.  The convertible is a rattle type car but its one of those things they need to fix.  If the dealer cant help then call the Volvo hot line and they will get involved.  Roger
