Knocing/Tapping from inside the coupe C63 AMG
I have this little problem/irritation about my C63 2009 with 130.000 Kilometers.
The problem is that the car has some knocing, ticking, tapping from inside the cabin. I hear it very good and this sound appers only when the car has been driving for hors and i stop at maybe a parking and put in P, N or just push the brakes in D. But the strangr thing it sounds like it is from the engine but when i pop up the hood i dont hear anything in the near of that sound. Just small ticking from the engine like normal.
I really dont know what this is. But i have done a video and uploaded it to Youtube. The link from the video: (please turn up the volume)
Please help me!!




Personally I think it sounds like the exhaust pipe making contact with the floor of the car but it is hard to tell from a video.
Good luck and hope you find the issue. Keep us posted

I also think that the issue is from the exhaust. I will check it maybe today or tomorow. Lift the car start the engine and locate the issue. It is very irritating when you hear a sound like this but cant locate it

I hope i can find something and also help you. I dont have any warranty but if i had i would give it to the dealership directly.
I will keep you updated.
Thansk for your post

Thank you very much, if its not from the engine i can take it! Thanks again
Energiiz, I've located the general source of the sound, I can hear it loudest when I'm outside the car and stick my head into the driver's side footwell area. Sounds like it's coming directly from underneath the car on the driver's side, so I'm thinking it's an exhaust leak on that side. When I put my head down into the passenger side footwell, I don't hear anything at all. Let me know if it's the same for you.
