BG GARAGE: Mercedes-Benz GL 550 No Crank No Start No Communication!

Wife went to go start the car outside, BAM warning lights everywhere, no crank, no start dashboard is a christmas tree!
Follow along as I dig through to figure out the root cause.
I lost a couple of video clips along the way, apologies if the video seems a little choppy, had to make a story out of what I had been able to record.
Be sure to subscribe to find out if the fix is able to bring this car back to life!

I just finished chasing my tail on an ML 350 Bluetec was a pass side module shorting to 12v on the can high. Also just like yours, just a single warning at first... Eventually the vehicle is down and wont do anything.

Very good info. I have similar issues but don't have the blind spot opt. Any suggestions ?

[@fundamentallybroken4194]

Can bus system connects almost 30 different modules on these vehicles. Any of those modules could be failing/ shorting out/getting shorted with water.

how do I remove the panel to get to the module

Pull the wheel liner off, crawl under and in the bumper cover youll see them tucked up on the sides
