2017 C63 Engine Knock/Tick Sound
I have a 2017 C63 with a weird Knock/Tick sound form the motor. It goes away usually, but comes back on cold starts and when the car is still warm and has been sitting. I took it to my mechanic (He's a certified master technician for Mercedes with over 20 years experience). He changed all the pulleys and both of the belts. Sound went away but came back. We are both stumped. He has called the dealer and talked to other mechanics at Mercedes and none of them know what the sound is. Any help would be grateful. Some other posts say it might be timing chain guides, but those posts never followed up with the fix was. Oil was recently changed also. I've attached a video. Car only has 32,000 miles.
Thanks!!!

And how long will the new timing chain guides last until they play up again after they're fixed?? Hopefully there will be more developments on this fix in future etc.
Us and our 100k lemons eh? 🍋

In b4 AMG GT Black Series exhaust rattle topic starts in the C190 section
