Yes i thought the Same change the Gateway Module with a scrap second Hand.
no sucess
als Bcm2
and Board Module
Ezs / Elv

all without sucess. The only Modul you can read is ECU Engine and Gateway

Dash and Mmi are also dark. If i Push the Button on Dach i can read km

i Buy a Trecker and Sensor to Check wire.
and we have a Problem with the doors only left side. This dont open and close with remote. All other do it

so I think it is a short circuit in can on left side
