(Posted by JustAnswer at customer's request) Hello. I would like to request the following Expert Service(s) from you: Live Phone Call. Let me know if you need more information, or send me the service offer(s) so we can proceed.
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 1 year ago
oh wow, that is very unusual, so first thing i recommend, access the battery, which you have done, there is a control module right there called a front sam, it has a lot of plugs facing straight up. unplug the module and see if the lights go off and if there is water or corrosion in the control module connections.

just unplugged aux battery ground feed at neg battery post (brown wire on spade connecter) to get wire out of way and noticed all warning lights stop flashing and every thing is back to normal. started vehicle aux. bat warning on dash as it should be. will still unplug front sam and inspect connectors,,
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 1 year ago
Yes, check the sam, the aux battery is only tied strictly to the ism . and the eis. that is it.
