SBC noise MY03-06
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.
If you want a copy f the DTB to present to your SA private mail your email address.

Thank you Konigstiger for this. I had Serv. B done, and also gave them the DTB u provided. Covered under warranty. As you said, it does not eliminate, but does reduce the sound. It is still noticeable, but not as much. Thank you.

EPC -> VIN -> 42 brakes -> 090 brake lines -> suction hose
If part #A2114208826 is the only one listed, you already have the hose with double dampers. If not, and more than one hose is listed more than likely you will need to upgrade.

I had this upgrade done today and it really does quite things down. Thanks again Dan for a great tip!
Hose part number has been updated with a -05 at the end. They also replaced a ring, gasket and cap.
Here's a pic of the new hose ( I assume you know what the old one looks like if it's on your car) :

As a followup, I'd like to say that the noise has diminished even further from "not as much noticeable" from my quote above. I am very pleased with the improvement. Thank you again Konigstiger!

Hmmm, this is how my hose looks. sorry for the crappy pic. had to use my phone
I remember having the damper changed, but it's gotten louder over time. Oh and one time after they changed the damper they changed my SBC pump so hopefully they didn't put an old hose back in.
EDIT: Deleted the old one. Will post new one shortly

Here is a better pic. Lol Iphone 4 vs Blackberry Curve 9300 (the camera is sh*t on my phone. 2mp, no autofocus, and no flash i miss my Bold 9700).
Ok back on topic hmm i think it is the update one but it has become noiser as of late versus when they changed the damper back at about hmmm 30XXX miles

update: so i still thought the sbc noise was still a little too loud even with the new damper. about a month ago, "brakes visit workshop" message would come up on the cluster (not in red). my indy shop checked it out and said the pump was good but the sensor was bad. once the sensor was changed, braking quality/feel is much better (feels more like a regular ABS system such as our 02 CL500) and there is less noise imo.
