E53 Gone Loco ***SOLVED***

It's reminding me of a shorted oil level sensor knocking out the buss.

Pull the rubber boot out of its mount holes going to the rear hatch. I think there might be two but look first at the right side.

The wire bundle in there will commonly self destruct. Mine had a few wires with the insulation rubbed off.

Can't read modules is a suck start point because the first step i recommend is look for shorted switches with the foxwell.

My rear hatch switch would short when it rained. I would see it on foxwell as "pressed".

Can you get to no modules or just some?

Typically when a problem it won't read the VIN and you have to manually enter model. Often you can get places you otherwise can't when you go that route.
