2001 Mercedes Benz SLK 230 noises
I am looking for your opinion regarding what can be the sources of these noises. The main concern - there is a steady medium pitched rattling noise that is possibly coming from the engine. Towards the end as i close the door, inside there is a hum that sounds like its coming from the back window but in the trunk i dont hear it as much. any opinions will be appreciated!
