Hi to all,

I bought a 2015 C200 bluetec in september as brand new. After 700km, a rattling sound started to come from engine. Vibration starts while car is on D at idle. When I hit the gas pedal sound goes normal. Also, it rattles while passing the speed bumpers. The noise came from airfilter(or intercooler) hoses.
I go the service for several times but still no solution. Service changed the parts, but nothing changed.

My car is at 3500km now and I'm still using it with this noise. I'm about to get crazy or burn the car.

Please share your opinions and help me related with the problem. I marked the vibrating hose with red arrows on the picture in the attachment.

Thanks in advance..

Not that it has anything to do with the noise, just wanted you to know that your engine is a Renault motor.

Using a Renault based engine cant be an excuse in such case. It's a Mercedes, not a Renault. I need a remarkable explanation.

The OM626 is used in a number of Mercedes models today, unfortunately it has found its way in the W205 (C200d) as well.

I know which company is making the OM626 coded engine. I just want to find a solution to my problem. Information about the manufacturer of my engine is not a solution. I also checked Renault and Nissan forums but nobody mentioned such kind of problem.

Are the MY2016 Vance 300's being equipped with these engines? (Gasoline, not diesel)

Problem solved finally..

Exhaust pipe doesn't assemble correctly while in production. Exhaust is so tight and close to the body. They reallign the exhaust pipes and rattling noise gone.(I hope forever)

So, there is no problem related with the Renault Engine.
Also, we wish to drive a C63 but Turkish government doesn't let us to drive them because of high taxes. Just FYI, I paid nearly the same price to my C200 Bluetec with a C63 sale price in US.
