W204 C63 AMG - New Purchase - HELP with issue please

[Zaq-AMG]

Hi. Newbie here so first of all i hope you are all well, i’m zaq and just purchased my first AMG, 2012 C63 AMG. Not had the car long and seem to have recently noticed a weird whining sound coming from the engine bay. I’ve put in a link to a video, it’s a cold start so you can sort of hear the whine in the background when the RPM’s settle down. If not I’ll try to get a better video.

Any input would be much appreciated and apologies for if i’ve posted in the wrong section

Alternator , water pump . ?? Seems to be definitely in time with revolutions .

Thanks. That could be a possibility, was thinking could it be one of the pulley’s maybe?

I’ll try to get a better video of the front end.

Try spraying each pulley one at a time , if the noise goes , there's your problem.

Better quality video, the whine can clearly be heard quite prominently.

Someone may be able to point you to a trusted Mercedes specialist (indy) who is far more able to diagnose your problem.
It's not easy from a you tube sound clip to be accurate.
