Simple, just put it in a container full of rice for a few days...





Seriously though, I'd say your chances at recovery are better if it was flooded in freshwater. If it was salt water, I think you're boned. I've actually recovered many electronic items from freshwater flooding, including a Roomba that spent 8 hours underwater. You need to make sure all of the electrical circuit boards and components completely clean and dry, which on the Model S is going to be tricky!



For high voltage, I think you're probably ok. Its the circuit boards and low voltage stuff that's going to give you trouble I think, because water can jump those circuits much easier at those small scales. If it were me, I'd be planning to take the entire interior apart with the goal of cleaning and drying every low voltage system on the car. I would keep my fingers crossed that the battery remained sealed and no water go into it, but you'll have to figure out how to test the condition of the battery.



I've got no experience messing with any of the computer systems in the Model S, but I have lots of experience with computer hardware and electronic bits and bobs.
