One problem related to manifold/header/muffler/tail pipe has been reported for the 2008 Mercedes Benz CLK350. The most recently reported issues are listed below.
Many owners of late-model mercedes-benz cars equipped with 3. 0l and 3. 5l v6 engines (m272 or m273) have experienced performance problems that include poor idle, loss of power and a check engine light with a p2006 code (or sometimes other codes). The shafts will fail inside the manifold and bind, causing the lever to break and the caps shown to look like they are popping off the manifold.
