engine noise while idling
low mileage 2021 c43. I have noticed this noise over a year. Did not let the dealer check because they asked me to pay diagnosis fee if no issue found.

This doesnt happen every time. But would like to resolve it before warranty expires... Has anyone experienced this similar issue?

It is common. The good news is it is easy to replace yourself and a cheap part to replace. It is the pressure transducer that needs to be replaced: https://mbworld.org/forums/c450-c43-...ml#post8508372

Thank you for taking a look! I think I saw this video as well and was not 100% sure. Since mine is still under warranty, the part and labour cost should be covered I guess?
