'13 Battery Disconect
Hi, I have a late built 2013 S550. After disconnecting both batteries, is there anything I need to reset (besides radio/settings/seats). I feel in the past there was something with the sun roof or windows? I cannot remember and didnt see anything in a search.
Just disconnecting batteries to do some welding on the exhaust today.
Thanks.

Solid state non-volatile memory has been around for decades. Does anyone know why these features are intended to forget? When replacing a battery, I use a power accessory with my Noco battery charger that connects to the OBDII connector and keeps the ECUs powered during battery disconnect.
