Grrr Sound on Under-Carriage

[Guest Lim BS]

Dear Members,

I am a newbie in this forum. Just got myself a 05 W211 recently and found that there is a Grrrrrr sound on the under-carriage when driving. Is this normal? Kindly advise.

Many thanks!

Sorry guys... perhaps I should change it to a vibration, when I stepped on the brakes and the car is stationary.

it could be the "SBC" is engage and then the sound comes after the brakes are disengage..Bro are you familiar with "SBC"

2005 got SBC in E class? dun think so for singapore side.

however the problem lim speaks about sounds oddly similar to the SBC / HOLD vibration problem encountered for the W211s.

or it could be engine mounting age? my 05 cclass also going thru such vibrations.

willy, all Pre-FL models all have the SBC, actually from launch day already got le, my previous Pre-FL W211 also have it & kana recall for SBC issues.

Hmm, sorry don't know 05 one don't have leh.... anyway i am driving 06, maybe LIm you step hard twice on the brakes when car at "D" stop and then check if your car has the SBC displayed on the dash metered ..if it says SBC "hold just your car has it and not to worry lor

Hmmm... actually the vibration comes from the brake pedal, and it lasts for a couple of seconds. It happens in both drive and neutral positions

Thank you Willy... that was very informative. So its the SBC... a technology problem. It looks like quite a rampant issue if so many owners can having this complaint.

when merc first launch the W211 in 2002, they make a big hoo ha highlighting the SBC Brake System, like stating it is a milestone for automobile braking technology, but during 2004 to 2005, there was a global recall for the SBC issues & this SBC feature was drop when they introduce the FL model. if i am not wrong for the FL models, it was replaced by hydraulic brake system instead of the Electronic brake system that are in Pre-FL models.

more info here:

http://en.wikipedia.org/wiki/Sensotronic

Sensotronic Brake Control (SBC) is a Daimler AG brake-by-wire system first introduced on the R230 SL-class, which went on sale in Europe in October 2001.[1] In May 2004, Mercedes recalled 680,000 vehicles equipped with the system; in March 2005 1.3 million additional vehicles were recalled. Mercedes decided to drop the feature altogether in higher volume models, such as the E-class. Lower volume models continued to use Sensotronic due to the high cost of redesigning a braking system.[2]

benz engineers apparently didn't subscribe to if-it-aint-broke... and we are paying for their mistake. unless the original owner(s) got it remedied under the warranty period, you will have to pay $600 for C&C to fix it for ya now. the shuddering is so annoying that i think it is money well spent but you may feel differently.

[Guest Lim BS]

My no... i'm surprised the owner didnt get it remedied for the entire 4.5 years he's been driving it! Irritating as it may, i've gotten a bit used to it though i am tempted to bring it in to get it fiixed
