As I understand it, this guy is a BMW master tech. (I think...I like his posts and inputs..thx).

OP- when you have two dissimilar metals- like when a copper wire is crimped into a metal pin in a connector, and salt gets in their, it will cause corrosion due to moisture in the air and galvanic action- over time this corrosion causes the contact to become intermittent when the actual copper looses contact with the metal in the crimp, essentially 'insulated' by the corrosion.

This is why people have posted that 'freshwater might be OK'...the salt is like metastatic cancer, it can crop up later unpredictably.

What is challenging, you can undo the connector and it looks good- but you need to look into the actual crimp on each wire in each pin of the connector....

Mein Auto: 2013 X5
Well the X5 was not as bad as I expected. Once I took the seats and door panels out an started following the wiring from the battery and changed modules coming in the way, rear fuse modules, lift gate module, fuel pump module, motors and modules for the front seats, windows(front and rear), front fuse panels and the main power module, engine module(under hood), spark plugs and wires. It came back to life except the main headlights which I knew needed the modules too.
Before I could put all back together, and start the 5 series an exporter offered 30K more for both as is, and i let it go!!
He shipped them to middle east I guess..
Since the vehicles were totally brand new it was not as hard or complicated as most people/experts here suggested. Most IMO had never opened a car before.

wow, that was fast. Thx for the update.

Getting the car running isnt the hard part- having it run for 5 years without issue is the trick...and that we dont know from your experience

Thats true. But Most of the body and parts are coated pretty good. Open connections, seat and door motors, and modules sustain most damage in a salt water flood.With all the seats and door panels, and carpeting out, cleanup is pretty thorough. Only thing I could not red rid of in my few days of restoration was salt residue on the aluminum in the engine.

Also except the main fuse boards, and power supply module, other modules from older E70's(like lift gate, door, seat motor modules etc) worked fine
