Noise while braking (not coming from pads/rotors)
Yes, I've searched and found nothing that is similar to my case
This noise only occurs when braking regularly, not to hard and not too soft. Sound seems to be coming from the passenger side dash or engine bay. The sound comes on and off again for 2 sec intervals, begins at about 10 mph down and lasts until the car is completely stopped. It sounds like some sort of vibration or buzzing sound.
Any ideas? This only started occurring about a week ago and is driving me nuts.....
TIA

You might want to check your wheel bearings. I had similar noise on my M5 when I had it last year. I ruined two sets of brake rotors because of this. It was all covered under insurance, but they couldn't figure out what kept warping them until they went for a test drive with me and I made them listen to the noise. They knew what it was the moment they heard it.
Hope this will help! GL

I'm guessing it's related to the SBC pump. Some noise is normal as it builds up high pressure. If you think the noise is not normal or excessive....
Humming/buzzing noise during pressure buildup from SBC system
E-Class (211) MY03-06, and CLS (219) MY06
Under warranty:
Mention DTB P-B-42.46/27e the single suction damper is being replaced by a suction hose with integral double suction dampers (part # A2114208826). In the process, they will bleed the SBC system with Star Diagnosis.
Out of warranty:
Make sure all service campaigns and recalls have been applied to your vehicle, have the SA check your VIN in VMI. Normally only service campaigns and recalls do not expire - honored always. DTBs are only honored under warranty and/or extended warranty. However, in this case a part was modified for better brake performance (i.e.: eliminate noise) therefore, it may be worth your while to request a no cost goodwill repair from dealer and MBUSA.
