Unhappy Command System Rattle

I have a rattle in my Command System on my 2017 C300 4MATIC has anyone else had this problem. Dealer has ordered part, but I am amazed this has happened on a new car!

Might have better response from W205 forum, but I had a 2017 C300 as a loaner (less than 5K miles) and it had all sorts of rattles, especially after being parked outside. Many of it was coming from the central part where the HVAC controls and COMAND screen are located. The interior would rattle and click as I drive down the highway.

Thanks for the reply, its not a Bluetec its a Canadian Petrol C300 4MATIC Seems odd the rattles came after being parked outside! Mine is kept in a garage. It goes in to have the Command System replaced and reprogrammed on 18th September, so I will have a better idea what happened.

My hypothesis is that Mercedes used cheaper plastics for behind the scenes parts in the W205 and they are expanding and contracting quite a bit while parked outside in the heat/cold. Unless they changed what the part is made out of, you might still have creaks and rattles after the replacement.
