Help! Our 96' C280 (80k) has started making a whining noise as of last night. When I opened the hood to locate it, it seems to be coming from a black box in between the black intake manifold, the noise is a sort of ticking sound. Any idea's?
Also, I assume I need Metric Allen wrenches to remove the cover? What does this box do? Is it safe to drive until a replacement can be obtained?
