Hi there
I've asked this on a facebook group been told its a possible cooling fan?

When I'm in traffic a couple times I've had a loud fan come on that sounds like a vacuum cleaner coming from the drivers wheel side?
 
Sounds like the engine fan to me. - Do you only hear it when the coolant temperature starts to rise?

Especially if you've been driving hard then have to slow to a crawl?

Post a video if you want the experts to give you their opinion (I'm just guessing).
 
I get this on my C32 and my dads C63 fan comes on when it reaches 90C I think? It also stays on a while after you switch the engine off.

In the 32 when I stop to a stand still the fan comes on and as soon as I let go of the brake it turns off.
 
Have you checked to make sure it's not a vacuum cleaner stuck there?
 
Completely normal. Secondary engine fan coming on. A software update may be needed as some cars come on at lower temp.
 
It sounds like a vacuum cleaner though.
Did you manage to find out what the problem was mate? I've only owned my C63 for 4 days and this same fan noise is really annoying me
