Your Mercedes
GLC300 2020 M254
Hi,

I have a problem with my GLC 300. It is an M254 engine with EQ boost. It has a strange whine that can be heard mostly from inside the car. You can hear it on the Video :
The sound also seems to appear for the short time after cold start. Did any of You hear something like this, do You have any idea what can it be ?
