PS... Autobox rolling back...
Oh, and PS......
My E350cdi will roll back - more than just a quarter turn of road wheels taking up slack in shafts/gbox etc - if on a slope.
Does it in C definitely, don't know about S because I never use it.
I had assumed this was just a "feature" of the car and was thankful for the brake-hold feature, rather than using the stupid foot-park-brake.
Erm...... if it shouldn't roll back , should I get it looked at ? Not very used to Merc's.

In that case, are you the people that get right on my nerves when I'm behind you at lights / junctions at night and all your brake lights blind me for as long as I'm there??
Use your handbrake!!!

I have it on the S-Class and it's great in the London traffic, when i drive the CL i really miss it.
Brake lights at traffic lights.
Brake lights on at traffic lights ?
Errr... Guilty as charged... sort of.
I do use the stupid foot parking brake if (and maybe go to N) if I know I'm to be stopped for a bit. I don't like the foot park brake much, I don't really see why MB think this is better than the handbrake lever (or push button engage & autorelease on throttle that some other posh cars use). And I presume the extra pedal it must be a right pain in the @rse on a manual gearbox car. Oh well, Whatever !
But I do use/like/find convenient the normal footbrake brake-hold in stop-start traffic and busy roundabouts. Particularly as it seems to avoid that 1 sec delay on getaway when you hit the throttle. I'm told this delay is only a "feature" (?) on Blue-Eff models ?
But on the plus side... at least on the steering column shift car, I don't flash my reversing lights at the car behind going from P or N to D.

Was that to me ?
I haven't a problem with the brake pedal.
Other than perhaps I'm too lazy to keep my foot on it while stopped.
But - as I have said - the main reason I like the brake-hold function (which is what this thread is about, sorry if I have drifted to other related topics) is that it prevents that tricky Blue Efficiency delay at roundabouts and the like.
And yes, I find it more convenient to use when manouvreing than the park brake thing to prevent any rolling back [or forward].
As to the park-brake. Well, OK I don't like it - maybe I'll get used to it. I still don't see why it has to be different to pretty much any other car on the road - I don't see what specific advantage the design has. But it isn't a problem - just something I'm not used to.

I don't believe there is anything to stop an ordinary automatic rolling back except the inherent forward creep when in drive. I've driven autos for 30 years and I imagine all would succumb to gravity on a steep enough slope whether it be a downward slope whilst in reverse or an upward slope whilst in drive. I've always stopped cars on the brake as I don't imagine two tons of car forcing the transmission to turn "the other way" can be helpful but I've never thought the fact that it could happen might be a fault. Some cars creep more strongly than others (is that torque related?) so some will roll back on a slope more readily than others. I may be totally wrong.
Yes, thats pretty much what I would think too, Toodeep. There is a one-way clutch in auto-boxes I believe, but I don't know how much backlash is involved along the entire drive train. Clearly there will always be some movement possible.
My comment was in reply to several other posts earlier in the thread about whether autobox cars will roll back - or not depending on whose post. I was simply stating my did (like some others on here), and as some seemed sure it should not, then I asked if I had a problem. By the way, I also think this is to do with the Blue Efficiency declutching the torque converter at standstill - presumably then one would have no "creep-power" [for want of a better description] holding the car via the TC.
And thats one of the reasons why I like the brake-hold on the foobrake - which is what the thread is about. It's easy and convenient. Perhaps I should use the foot operated parkbrake when doing a 3-point turn on a hill, but the brake-hold does it easier.
BTW - I must be coming across now as not in favour of Blue -Efficiency... I have made a number of comments I guess relating to the percieved [by me !] downsides to it. But I haven't anything against B-E really - it's just that these points have some relevance to the topics I have posted in. Happy enough with it all before I get labelled as a knocker.

I'm with you on the foot operated parking brake. It gets used when I reach my destination . . . and that's it. Perhaps I've subconsciously avoided 3-point turns on hills. Because I drive several cars, I never quite get used to it. It's not the pedal or the release, I think it's just 'brake on' and 'brake off' being in two different places is counter-intuitive. This is especially so on RHD cars where the two are on opposite sides. The one time I've driven a LHD Mercedes with the pedal and the handle on the same side, it was somehow easier. I haven't experienced Mercedes' Hill Start Assist or Brake Hold functions but I owned a Range Rover Sport in 2005 with an electric parking brake that released itself when the throttle was pressed. I thought that was genius and the Mercedes system sounds even better.
On Blue Efficiency, I'm getting an E350 Diesel Coupe and have to say I don't like the sound of a 1 second delayed reaction to the throttle. I'm hoping it was a slight exaggeration on your part. In practical terms, I doubt the delay is any worse than what we took for granted a couple of decades ago but the car is mainly for my daughter and its safety systems are a major factor in my choice. A 1 second pause sounds anything but safe. You suggest this brake hold thing seems to get around it but the delay issue is still a 'feature' I'd rather do without TBH.

I use my SBC HOLD quite a lot, though I rarely use SBC STOP as it causes far more stress than it allegedly prevents, the version hooked up to Distronic would make more sense.
What? They put SBC on W204!
I hope the SBC pump is reliable.
SBC Hold is for leg free those that are too lazy to hold the brake or put on the parking brake.
You are missing all the new Merc gizmos and high techs and also the unreliability sides of Merc.
Read your owner manual, all 300 pages of it and try it out.
Hi Toodeep.
Yes, it was the Land Rover auto park brake I was thinking of when I made the comment about some other cars - don't know about the RRS but I had a Discovery on loan for a short while (don't ask why - it still hurts !!) and thought it a bit more 21st Centrury and it worked well - but apparently the Land Rover system is a byword for unreliability. Oh well - I guess you can't win 'em all !
As to the Blue-Efficiency delay - well sorry if I had made a bit too much of a meal of it. It's more of an irritation and something I'm getting used to, rather than an out and out problem. In the end, I guess it just needs a bit of anticipation - like being in a manual car and selecting first with clutch held down and hand on handbrake ready to release, as you see a gap approaching. I guess I mentioned it because my previous auto box car was happy to sit there in D (without rolling or creeping too much btw) and then go when you hit the throttle. So the Merc feels different, and it IS something you need to adapt to.
A full second maybe a bit of an exaggeration - like I said earlier, when I was less experienced with it, the time delay seemed inversely proportional to the intended gap size - I think that was a mental perception !
Otherwise - you (or your daughter - will love the car. It is a damn good car.
Hi PeterDLM,
As a Merc newcomer - maybe I'm not too familiar with the Merc terms that get chucked about. SBC Stop - by that do you mean if you brake quite suddenly, the car slams everything on and scares the sh1t out of you ?
Again - many cars do something similar now, something else to get used to.
I have Distronic too, but not really used it a lot yet. Still a bit nervious of it, and can't make the mental leap of faith required to trust it to a standstill ! The majority of my driving is local town stuff. And of course the radar or whatever only looks at the car in front rather than a long way up the road, so I prefer to look after that side of things myself. Perhaps more useful on the german Autobahn where one see's a train of cars all screaming past at speed in close convoy ? And - it seems to me - with better lane discipline on the fast roads ! [ Ooops - that'll start a row for sure !... sorry].

Quality info. Cheers OP. Mines an E 220 2007, {I think that's a W211} puts HOLD on the dash. Is there anywhere on here with loads more tips & trick pls 
Ok I have just tried this in my C63. Up a slope, in drive mode, if you take your foot off the brake then and it holds for a few seconds (I assume to give you enough time to move your foot onto the accelerator), and then it slowly starts to creep backwards...
