Hello
I am writing from Turkey, I have just become a member..
My problem is a strange sound and I still haven't solved it. He added the video in the link.

I am no expert but it does sound like the very known problem of the cam chain tensioner.

X2 on the cam chain tensioner. Stop engine until it's replaced. Likely the noise will be gone but if not you have eliminated the most likely and potenially disastrous cause. Search on this site, tons of info for you.

That sound is also heard at the end of the video when the engine stops. I think the problem is the same.

Wow, I have nothing to add but agree, that is an odd sound! And my wife and I will be in Istanbul next month.

I have a similar model C400GT but I had never heard a sound like this, please check the whole transmission, sound it is not good symptom and could be worse, stop immediately and check

Hello, I found out today that the problem is caused by the exhaust. After removing the final muffler, the sound went away.
