W211 E320 CDI estate command module

[MarkOC]

A few weeks ago I replaced the front discs on my car. I’d ordered the wrong size discs and so I left the front end up on stands. When I eventually replaced them, after about a week, I dropped it back down only to find the battery completely flat, no power at all. I’m assuming I left it locked when I lifted it and the alarm thought it was being lifted away. As the siren isn’t working I didn’t know it had activated. Anyway, I recharged the battery and after a few runs everything was working with the exception of the sunroof and the command module. Eventually the sunroof started working again and then the command module. I went away for 5 days and came back to a flat battery again. So, believing the battery to now be faulty after going completely flat, I replaced it. Now, again, the sunroof didn’t work properly at first but now it does, however the command module still doesn’t. Is there a reason why after replacing or disconnecting the battery this happens? And is there a way to force start the command module?

Comand units have a tendency to stay on -
They drain the battery and lead you to the situation you’re in.

Charge the battery, I’d get the software updated in the Comand unit and see from there.

doubt you can update command on a 2003 car now.

Never had any issue until this happened. Would changing the command unit for an android unit make a difference and would the clock still work off of an android unit?

After a battery being flat / replaced often windows and roofs need to be cycled fully open / closed, even pressing the button for maybe 20 seconds, to reset parameters.

If you go for an Android you will enjoy masses more functionality, but the Android will not update the clock as now. Each 6 months you would need to re connect the battery (at midnight if 24hr clock is important), or have the clock set via Star.
I'm not sure if the menu facility for clock adjustment is removed on a 211 with Comand, but it certainly is on the 639. So I use Star to set the clock each 6 months. Our 211 never had Comand, but now has Android (as does the 639).

the clock doesn't update correctly anyway ?

it is stuck on the wrong epoch and doesn't know the date within 6 months, let alone the correct year which then impacts the outdated list for british summer time change over - but, when in grown up land - the hidden - manual choice is 3 clicks every 6 months and its correct....

I was just playing with this auto date and time feature - that was never on on my father's car - using dealer diagnostics in the cluster, on his car it was NOT set to a specific country, and had left the cluster menus slightly customisable - so you can get what you need on one screen - when I selected Great Britain and said code, it stupidly change the menu layout forcing the digital kph alternate speed display where I used to have Temp and enabled the stupid and confused auto time and date

fortunately the auto wrong date (that's now stuck in year 2003 due to the wrong epoch from the last 2019 WNRO event ) is a cluster option to disable from auto to grown up - then the time and date becomes a choice of auto wrong or grown up manual operation, where it all operates correctly - but the crappy GB setting has locked the kph display and I can no longer code the cluster to European allowing me to get the temp back where it belongs ( I can get to temp but only following a mad muddled set of cluster insanity and its only on its own screen...) I expect I'll get there but three times with Xentry I coded back to grown up land but it knew best...

idiots the lot of them

so sussed it - had another play in Xentry

if the cluster region is set to "Great Britain" in today's world you get three unhelpful changes - it hides the ambient temp display (till its only available via mental confusion toggling menus to try and find where it hides on its own screen), and it also replaces the option of kph or temp in other menus to kph only, AND sets the default clock setting, to Sat Nav time (but its is switchable back to manual within a horrible cluster fight)

my fathers car had previously been set to cluster region "--" AKA no region selected and was better. But I was unable to re programme it back to this. But having realised in other options on other Mercs they don't let you pick the "--" option - you have to try something else. So I picked ROW (which automatically decided I wanted in sub menu English Miles) and everything is back to the better options it had before I fiddled.

This update away from "Great Britain" is worthwhile - Nav time and date is now always wrong due to the Satellite April 2019 WNRO event as no one has made a patch. Thus you no longer want auto time and date, as is muddled gibberish (from Satellites via the Nav). Choosing ROW for the cluster sets the clock to a default manual operation. And allows the Ambient temp display to show in most of the menus on the cluster. (with a fight you can toggle that back to miniature kph digital display rather than temp, if you choose to drive on the wrong side of the road.

its really stupid rather than having additional menu options, they just swap one user screen between temp OR kph - why on earth can't I have both
