I've been combing the threads to determine if my particular vehicle is affected by this issue or not.

Car build date is 06/22/04, deemed a 2005 model. I have the VMI print out and the only SBC related work was done under recall; 2005110001 - the bracket and grounds.

I have verified, visually, that the bracket and grounds have been fitted. What I do not see, however, are any suction line dampers. Not a single one. In fact, the only thing I do see is that there does not appear to be a clamp on the end of the suction line that connects to the metal tube to the right and down of the underhood battery compartment. Indeed, if I tug lightly on the suction line it will slide up and down on the tube.

Looking through the recalls sticky, using my VIN, it appears that my vehicle is not a candidate for the SBC suction line damper(s). SBC seems to be working fine (although it certainly won't win any awards for outstanding brake modulation from the pedal) but it does make noise; it's not unbearable.

So what's the deal with the suction line dampers? Will the dealer install upon owner complaint about SBC noise? Should there be a clamp on the other end?

Thanks much,

Dan

hope this helps. This was done to reduce the humming sound of the SBC system. The first day, it was reduced, but noticeable. Now its even softer.

I did see that one, gnma, but I cannot tell if the dampers are supposed to be installed on all MY03-06 cars with SBC, or only on those cars identified by VIN.

Thanks,

I just picked up my '05 E320 from the dealer. I had it in for a number of issues, one of them being the SBC noise. They couldn't replace the hose during this visit as they had to order it from Germany. They tell me that it should be here in about one week.

Regarding your question...I think it really depends on the dealer. The first dealer I visited, Lokey Mercedes, told me that it (the SBC noise) was a normal condition and refused to replace the hose. This was even after I showed them the DTB!!

I now take my car to Crown Eurocars. They are AWESOME!! I reported the SBC noise to them, showed them the DTB, and they took care of the rest. I'm looking forward to having the hose replaced next week.

Best of luck to you.

Check your email, sent a copy of the DTB.

konigstiger, can you send me a copy to please.

Not factory installed on any of above.

Once again, thanks Dan.

One more quick question regarding replacement of the suction line.

For this proceedure, is the brake fluid also flushed and replaced?

Reason for question is the car is also calling for Service C. If the brake fluid is flushed/replaced as part of the SBC suction line fix then I certainly do not want to get charged for changing the brake fluid as part of Service C.

Anyone know?

Thanks,

Dan

The only requirement when changing out the hose is to bleed the system.

If you have a good relationship with your SA, than I would ask him. I'm sure you'll work something out.

Funny, I had the hose done last month and I stopped by the dealer this past Monday and asked the servive manager that very question. Just so I didn't do an unnecessary fluid change.

His answer was that they always bleed the syetem (required) and that they can't do it without changing all of the fluid ( remember it doesn't hold all that much) because Star Diagnostics is programmed that way.

We shall see how good a relationship we forge. This car is new to me, my first MB, and first time to this particular dealer; Mercedes-Benz of Tysons Corner (AKA HBL). I presented the SA with a bit of a list of things to fix and check; wacky speedometer, SBC noise, water inside the trunk lid, occasional clunking from the rear (which may be my imagination), a constant whine from either the power steering pump/idler pulley/AC compressor, update the AGW and Nav (nav is on v.2004), Service C, and what appears to be a very slight miss at idle. A lot of which is covered under the warranty.

We'll see how much he likes me later today.

Dan, that isn't really clear whether ALL the fluid is changed (bled). It mentions bleed often . So does that make my SM right or wrong ?

konigstiger

See page 2 - decreasing pressure, item 3 “until almost fully removed”. SM is right in that it is the dealer’s call, and wrong in applicable SDS bleeding procedure.

Hint: To all those having this done ask if all fluid will changed if the SA says yes they are committed.

starbrite

Dan....I re read that again and interpret(ed) that as knob almost fully removed, not fluid.
Good thing I'm not a MB service tech !

konigstiger

Actually very little hands-on experience. But then again I have repeatedly admitted this. Now then, Friday afternoon - long lunch, restaurant with wonderful ambiance and beautiful waitresses, small viewing screen, third Glenlivet – well you do the math. Enough with the excuses with MB tech confirmation: Yes, all fluid is changed when bleeding the brakes through SDS.

All brake fluid will be exchanged with SDS bleeding procedure.

This is my first Benz too. You just don't know how much I had changed in mine car under warranty. Everything from the sun visor to littliest thing. $25 gas gift car can sometime goes a long way with you SA....you do understand right...showing a little appreciation that's all...I know I don't have too, but I would like too. If you drive a Benz, I'm sure that should be a problem. Now every time I come in, I asked him to change this change that, no problem whatsoever. Just little thought...

Took the car in for the SBC suction hose replacement. I picked it up this afternoon and noticed an immediate improvement in the brake feel. I can barely feel the SBC pressure build-up through the brake pedal with the new hose - unlike the original suction hose which at times made the brake pedal feel like a cheap foot massager. And the noise from the SBC is almost gone as well. I am very pleased with the results.

By the way...my dealer receipt shows that they "bled SBC brake system".
