Just bought my C240 2004a month ago. Does anybody know how to replace front side marker (orange) light bulb? It shows on the panel as a trouble. I saw a few answers about tapping on the light. May beI need just a new bulb.
Second question is about sound of engine. It seems it's comming from the exhaust(rear) not from the hood. Before I bought this car I went to Mercedes dealership in San Francisco just to compare my car with the one they had for sale. The noise was the same. Any suggestions?

 

the lens just pops out with a flat blade pocket screwdriver.

 

Thank a lot. I fixed it already. That was easy.
