HOLD
Depress the brake. Depress the brake again quickly until HOLD appears in the display. HOLD is activated. The vehicle is kept stationary without the driver having to depress the brake pedal. Braking effect is cancelled and HOLD deactivated when you depress the accelerator pedal.

If you receive message “Hold Cannot Be Activated!” the rear SAM is missing battery sensor data and battery sensor will be checked and replaced if necessary.

Thanks. Great feature; I will try this out tomorrow on my Bluetec.

I can't activate brake hold or get any messages on the MFD.

If code 807 lists on your datacard the DTB applies.

AMGTTV8

So push the brake pedal in gently or normally, then release it, and pretty much push it down as hard as possible and hold until that message appears? Where do I find this 807 code?

AMGTTV8

Dont know what the datacard is...just looked through my books and found nothing.

pinebaron

I tried in my Bluetec today and it did not work.

cyclerider

My datacard lists this code : 807 AEJ 06/1/M/X

Is there a reference number for the DTB? My dealer usually doesn't know about these things without some help.

konigstiger

Check your email.

AMGTTV8

me either...damn it...this sounds so cool i want it to work, especially driving around chicago..

My datacard also lists SA Code 807, but the hold function doesn't work for me.

konigstiger

I was under the impression that North American vehicles are not equipped with the Brake Hold feature. However, after reading the DTB I am not so certain anymore. That is to say, if the datacard lists code 807 and the feature operates via the rear SAM in accordance to the DTB an assumption would be through SDS a tech could successfully program the feature to operate if not initially equipped as such. I sent an inquiry today – hoping for reply sometime next week unless of course another member provides viable info before then.

MY07 = 807 AEJ06/1/M/X (MY06 = 806 AEJ05/1;05/M)

amdeutsch

My build date is 07/06 (MY07) and I show 807 AEJ06/1/M/X on my data card. But I do not get either indication in my IC. Talking to my SA I'm told that code 807 for him shows Technical Modification.

Diesel Benz

Technical modifications as of model year 2007? Code 80x has always indicated the change of model year. Some odd changes might occur in the middle of the model year, don't know when exactly the brake hold was supposed to be release for the US market though.

For those looking for more info on this; here is what I found on the German MB site:

Adaptive Brake - English

This would be in owners manual wouldn't it?

Sounds like a perfect candidate for decontenting of USA models in order to cope with falling dollar.

My '08 E350 4Matic doesn't have it. It has a Feb 08 build date.

Diesel Benz

Can you explain how did you conclude your car does not have it? I mean it may not be straightforward to activate hold when trying the first time.

If MBUSA has a bulletin on it, someone I guess should have it. If someone has it, I guess a February 08 build date car should have it.

wmhjr

Sure.

1) It's not in the manual whatsoever - including in the online "newest" pdf version of the manual on MBUSA.com.

2) I tried both your method as well as that listed on the link earlier in this thread. No dice.

3) It's not listed anywhere on any documentation (marketing, presales, sales, etc) for the vehicle.

I'd really like to have it and hope I'm overlooking something, however I believe this is just another feature that is not available for we in the US.

Diesel Benz

This feature was available on Euro cars already before the face-lift. Not on the first sedans but from perhaps late 2003 onwards. So US has been missing it for a long time.

On the pre-face-lift car it was simply SW, not cost savings from leaving it out. I have not checked the face-lift part numbers, with traditional brakes this actually introduces some additional cost. I would guess leaving it out from US cars would not mean any over-all savings. Probably disabled with SW (or would anyone have looked at this in more detail).

It appears clear now from wmhjr's tests that this hold feature does not appear on current US E-class cars.

konigstiger

I reiterate:

Indeed, it is not in the MBUSA manual however, MBUSA released DTB P-B-42.45/97 MAR08 to correct a possible malfunction for this feature and this is this basis for my posting and bringing it to the forefront of everyone’s attention. I should note that the DTB specifically mentions SDS has a function check for the “hold” function. Have patience, I am hopeful I will receive a definitive answer sometime next week.

amdeutsch

And it is appreciated that you post this and other items of interest to forum members.

Yes, it is not in the manual. Therefore the instructions where linked. The only issue I can see is the fact that access to the US version SW seems to be more restrictive than the ROW version SW for those that hope to get this feature working properly or activated.

konigstiger

Understood however, my interpretation of the MBUSA document (DTB) implies that MBUSA techs do already have access to the corresponding SDS menu in order to diagnose malfunctions and as such, I would believe the necessary application to function code as well.

amdeutsch

But the still may have to get approval due to SCN coding.

Diesel Benz

Not all electronic control units are SCN coded. I did not check if Hold is covered by SCN in Europe though. Also, isn't SCN fixed for a specific car with the options list, or could a change in the SCN "release" a parameter for individual settings?

Anyway, will be interesting to hear what konigstiger finds out, the bulletin clearly indicates that Hold would at least be on the way to the US if not already activated on some cars.
