SL55/63/65/R230 AMG: Another battery drain issue / Where is the tele-aid module located?
Battery drains overnight and my key/remote doesn't work. Placing the key in the ignition doesn't trigger the relay to switch to the starter battery.
Only thing that worked was putting jumper cables on the electronics battery, and after waiting between 10min to 1 hour, the key would finally work.
Last night I noticed that my SOS light would blink every couple minutes and wake the command system. This is why I want to disconnect the module and see what happens. I pulled the fuses already, and the current draw was less, but it was still waking up constantly
Sorry I can't help with the SOS system.
