Rattling noise from engine when releasing gas pedal
My 2015 C300 only has 2800 miles on it.
The rattling noise can be heard when releasing gas pedal at every cold start.
The noise is loud like driving a truck.
And my C300 is vibrating when it is sitting still in the Drive gear . It is really making me feel uncomfortable.
The MB technician told me these are normal on 2015 C300, but I don't think so.
Have you ever had these issues on your C300?

I don't get any noise other than the normal DI noise. I do have an engine misfire every half hour or so of driving, it feels like that anyhow, I'm not sure what it is but I feel a slight judder now and then on the motorway at speed. Feels like one cylinder didn't fire. Just keeping an eye on it. Could be poor fuel or an injector.

I have similar sound... In fact there are a few thread discussing this sound. While dealer would say this is normal, I don't really agree... Thinking about filing a complain with BBB or something.
