I beg to differ, facelift 211 has a servo


Yep, but it has also stated that you cannot retrofit servo brakes to pre-facelift because lack of space. So there should be lot of changes in engine bay?

IMO I would not let the SBC scare you off.

I did open up the wiper stalk once, I did manage to put it back working, but I still couldn't fix the intermittent wiper turning on unintended, even though I cleaned off all the dusts.

You can't fix a wiper stalk, but are not scared of fiddling with the SBC? I suppose to experience fear, you have to have be aware of the danger, whereas you appear to be blissfully ignorant. I just hope that if (when?) it all goes pear-shaped, that you don't endanger any innocent victims.

and by the same token, had his car had a standard hydro/servo setup you would also say he was wrong for wanting to replace the seals in the master cylinder?

I'd not be too happy putting my life on the line when a repair to the brakes had been done by someone who failed to repair something smaller in scope, not matter what the technology concerned, and no matter who the individual.

I know many people who I would not trust to replace the seals in a master cylinder. The difference here is that they are also aware that they shouldn't be repairing safety critical systems.

Scary stuff! How many ten year old SBC equipped Mercs are going to be on sale in the future, but instead of having a worn pump replaced they've just had the counter reset? Ticking bomb......

Yes the unknown is the scary bit, certainly when "kerbside motors" buys an as seen car at an auction only to find the SBC has a problem he will not spend £2k fixing it, thats for sure.

Its not quite as bad as that, the SBC control unit will be doing self checks for pump pressure so in theory it should pose no greater risk than one that has not had the counter reset

Not really Mark, yes from the display point of view, but certainly not from the "Red Dash" no brakes point of view.

A financial ticking timebomb perhaps?

Something one could say about any number of units and systems in modern Mercs. The one thing you can be certain of is the SBC will need to be replaced at some point, budget for it...

Mercedes took the counter off in later firmwares, so not really an issue.

I read that the pump was good for 600,000 presses but Mercedes set the counter at 300,000 to be on the safe side, but I guess when people started complaining they revised this?

If MB did indeed remove the counter status in later firmware, then it would also be true that resetting the value to 0 on a non modified firmware achieves the same thing, with the same risk, or lack of.

Not necessarily, they might have added further checks into the firmware at the same time that they removed the counter. It would be better if there was a way to upgrade the firmware rather than just resetting the counter, but that's a different ballgame.

I'm not sure if I've understood the argument properly.
Are you saying that on later models fitted with SBC that the "counter" was removed, and thus later models are likely to get a longer life out of their SBC pump?
If this is true, have you any idea when the counter function was deleted?
I have a vested interest, as I have a November 2007 SL350, one of the last of the 230s, so I'd be mighty relieved if my SBC pump would have twice the lifespan of earlier versions.
Depending on your answer, I may be able to sleep soundly again!

All SBC units will have a counter enabled, just the later ones will already have the "extended" count limit applied.

SBC was still fitted during 2009 to the 230 including the new shape version, there has to be a counter as said

mine's got one :(

Hopefully David as the end of the line it is a much better unit, I took my 2002 SL to 55k and Gordon another 10k and no SBC warning ever
