Hey everyone, first post...also, just got my first Benz...2010 C300 Sport 4Matic... I just noticed that when the car is started there is a not-so-faint humming coming from the front vanity light panel. Has anyone experienced this? Has anyone had the panel off to see the innards? It almost sounds like when a fan in your computer is starting to fail. Any thoughts or insights would be very much appreciated.

Thanks in advance, and looking forward to speaking with some of you!

It might be the brake booster. Maybe you can get it checked out under warranty. If you still have warranty...

Could the brake booster cause a humming in the vanity light console? I'm talking about the upper panel with the sunroof switch, lights, etc...thanks for the ideas
