If you're hearing whining noises, clicks from the engine compartment, check your AC compressor pulley...Check it anyway because the last year of the W221 is 10 years old. This is from my 2007 S550 4Matic. I was meaning to change it prior to something like this happened and got distracted by life.
So this happened to me 3-4 months ago. I took the opportunity to replace ax compressor at that point lol.

I'm glad you found the glitch before it's too late . We had to replace my dad's (Cadillac Fleetwood , different car but principles of those are same ) A/C unit and it was having clicking noises as well as compressor was cycling on / off quite often
if u get the right part you did well to source one... I did mine about 5 years back at 50k miles the bearing was already getting noisy
the big circlip is a nuisance, few tools expand enough or get clearance to do in situ - otherwise its an easy 1hr homer
I'm working from below the car and have a good deal of room. I had to use a small puller to get the remains of the bearing off of the shaft and had just enough space.
