Thank you for the update, I guess unfortunately the mystery remains. What exactly happened to your front diff, do you mind posting the work order with your personal information blurred out or can you summarize the repair?
The whole front diff was replaced due to internal gears being shredded. The noises got loud enough after a pop and it became a clattering of sorts.

Ouch that sounds so bad, were they able to figure out why the gears ended up that way? I am glad they got it fixed for you though but still curious what happened and how it happened so you can prevent it from happening again.
Hi All. I had new rear discs and brake pads installed and the car drove perfectly - for a day. The chirps/squeal returned. I have been told to wait for factory modified brake pads. It seems like several other owners have the same problem.
Hi All. I thought I would give an update. The factory modified brake pads were installed last week, and I took the car out for a spin. The mouse and parakeet squeaks remain!
I did some more research and got some valuable comments on my YouTube videos. A few owners pointed out they have had squeak problems with the performance exhaust gas flaps squeaking. Not the brake pads. So I’m asking my local MB dealer to look into this now.

Very helpful to know. I hope others can avoid the one year 15+ trips to MB service wild goose chase. The car is otherwise amazing. Let’s see if this solves it!
Drove the car with the PE off and the squeaks still came. Therefore unlikely exhaust gas flap - back to square one. Must be how the rotors touch the brake pads turning. Modified brake pads didn’t help.
Hi, quick update for those interested. The rear calipers were recently changed by MB service and it helped some. However there are still squeaks at certain pitch and curvy turns. I would say 50 percent better. I have several PMs from owners with similar issues. Thus far this has been the most helpful adjustment.

Thanks for the update, shame it is still not fully resolved though. Glad to hear about the helpful forum members here.
Apparently, the mount hindered full retraction of calipers and on certain turns and pitch there would be some friction causing the annoying bird chirps and squeals. I know others have similar chirps coming from their cars. It took over 12 months and numerous MB service visits to zero in on this day one new car issue.

I see, thanks for your answer and again I am glad to hear the issue is finally resolved and that you can fully enjoy your vehicle again.

My apologies if I didn't understand you correctly, you said it is making the same noise as OP but not the same noise and problem, again my apologies that I wasn't able to understand. If you don't mind could you please post a video and/or explain in a different way so we can help you out?

sorry for the confusion, I meant I have the same noise as Ryan Li who posted his video right above my post. My car also doesn’t make the noise when engine is cold, only when fully warmed up.
