I have recently purchased a 2008 C class and the dashboard has started to make a rattle. I've located the source and it apprears to be coming from the centre grill on the dashboard. The parking sensor is located on the grill, as is the light sensor and if i apply slight pressure to the grill the rattle stops. Is it a straight forward job to remove the centre grill to find the exact source of the rattle or do i need a pick axe as the noise is starting to drive me crazy. Any help welcomed.
