this annoying squeaking noise started about 6mos ago. I hear it after the car is already warm and when I first take off.

It is not a constant squeak. It seems to squeak in tune with the speed of the rotation of the tires. You know, when going slow...squeak.........squeak......squeak. Then when I accelerate the squeaking speeds up in sync with the speed of the rotation of the tire it seems until I no longer hear it.

I took it to Mercedes last week and of course "they could no duplicate it, it might just be a small rock caught down there.".......

It's not my brakes...plenty of meat on there still.

I want to take it back to the dealership again but I need a better guess. I still have a full warranty.

Any ideas?

playfair

wobbling brake disk?

I recorded the noise...I am sending this to Mercedes as well. I have another appointment on Wednesday.

Issue is now fixed. I wanted to post what it was in case anyone else hears this. There was an LI bulletin that went out from Mercedes LI.42.20-P-052990. There are small springs that are visible after wheels, brake pads, and calipers are removed. They replaced those, no charge, and the annoying squeak is gone!

4 springs were replace, here is the part: 230-423-00-92 SPRING
