A few threads exist on the R172 SLK sub forum describing all sorts of rattles and noise from underneath our cars. These have been associated with the exhaust manifold (prevalent in the 350/300) as well as catalytic converters.... Mine has had 2 replacements of the catalytic converters.... (left and right)... in fact, the last one was just replaced a couple weeks ago. MB is aware of these issues and should do whatever is necessary to fix yours.
