I've noticed a low level hum coming from somewhere in the dashboard after a journey when I switch off the ignition. Don't hear any hum from outside, e.g. coolant fans.

What could it be and does it need to be fixed?

Thanks
 
Almost certainly a cooling fan for the electronics in the dash, which will run on a timer or a thermostat.
 
Ours has a hum too. I thought it might be the Comand hd on standby. Cooling fan makes sense.
 
Quite normal I think for noises after switching off. I've had a few cars that have done this.
 
My 2013 C180 does this too.
 
Normal as above
 
All sorts of noises eminate from mine when ignition switched on or off at end of journey.

Had the same with my previous E Class so I do not worry.

Most probably the cooling fan for the Comand. Mine does this after a long journey or a particularly hot day.
