Climate fan noisy --- common?
With the climate control fan at a low speed, intermittently I hear a quiet "ringing" rattle, suspiciously like a ventilation fan bearing going out. It gets started by a bump or slight turn to the left (gyro effect?). If I turn climate control to "Off" the noise stops.
So, I'm certain the fan is crapping out. I sure hope they won't have to tear out the whole dash to replace it --- great way to get rattles.
The question is: Is this a common problem with 2011 E550, et al?

Check all of your registers that they are all open. Every time I experienced noises like that, someone had partially closed a register somewhere in the car.

This is an easy part to get at, you drop the panel above where the passenger's feet go. You then disconnect some cables, a couple of plastic pieces and then twist the complete fan to remove. This is where the cabin filter goes so you can search for those instructions to help you, the only problem is that you have to get your head in the passenger foot well and facing up to see what you're doing.
Mine would make a chirping noise when on low speed and especially when cornering. Took it out and lubricated what I could, no problems since then.
