GLC vs C300
I have both a GLC and C300 and am very happy with both. I have noticed a brief engine noise on the C300 when I first start it and am coasting which goes away within a couple minutes. The GLC has the same engine and doesn't make that noise.
Any thoughts?

What year is your c300? There has been issues with early build C300 engines with problems with Pistons/rods. Problem with wrist pin. See the W205 forum. Cars are requiring engine rebuild. There is dealer/ factory bulletin TSB for this.

Thanks for your suggestion. I brought back my 2015 C300 back to dealer I purchased from with an audio clip as well as observation that my GLC does not have the issue and they finally confirmed the issue and are ordering parts. The other dealer who has been servicing the car had said the noise was "normal".
