where did water leak come from? you state where it ended up but where is actual water getting in?

Does it run on any modules or harness connectors?
Did it get under front seats?

My guess is a module got wet inside and is getting funky due to water shorting connections inside.

I know water been leaking from the right side of the trunk right under the rear windshield in that corner... but .. also they said that water leaked from the sunroof (i did not know that was happening).
and .. No. water did not get to the front seat or carpet.
Question: do the 2010 E350 have plugs, harness or modules under the rear right-side carpet? Or inside right-side panel?

I am sure there are modules under rear package deck...

go in trunk and look up under this package tray for signs of water...
my guess is it ran down wire into connector on module and messed stuff up.

ALso get codes read from all modules...not just ECM.

Ok. I look at the fuse box in the trunk, i dint see no sign of water.
I'll try to fallow the wires to see if there any water under or around it.

Let's see what happens .
