Hi brothers, I have e55 amg w210 model and I have got a problem with it which I could not solve it.
The problem is sometimes I get all window not working and if I disconnect the batery and connect again every thing will be fine, then after 1 day I get central lock not working and horn also, and now brake light working all the time..

B1054
B1055
B1057
B1059
B1021
B1023
All related to fualt in can communication with control unit DCM.

bader - please take of 1st-thing-1st - if I understand correctly - the brake lights on "on all-the-time" - is that correct.
If the Brake Lights are on all the time - then the Brake Switch needs to be replaced 1st - use genuine MB part only as the China-knockoff brake switch is not-good - it's not only a question of your brake lights - that brake switch is also a major grounding/connection point for startup.
On your other issues - a couple of things - if voltage drops below a certain point - yes - you loose some settings - the battery issue - make sure battery cables are clean - and clean the ground cable connection to the body and reattach that side of that cable. You might have the battery "tested" - with W210's there are gremlins that come up when battery is headed towards failure.
Also check that your ignition switch is "tight" in the dash - has round nut that needs to be tightly screwed so cylinder/connections behind are correct.
Leep the beat !
