OK So about 2 days ago It was a beautiful sunny day. I just finished making the funeral arrangements for my wife, and finally made it back home. I parked the car for the rest of the day and left my sun roof open. Fell asleep and woke up 2 in the morning to a really bad rain storm and my sunroof open. At this time I didnt know how long it had been raining so I just rushed to my car to turn it on and close the window but when I got in it Nothing came on. No Lights, nothing on the dash nothing on on the radio no door lights or nothing. At this point the car wont even start. So I put ply wood and construction plastic bags on top of my car. Its been two days and I am two days away from my wifes funeral and my car isnt running. Please help me to what I should Do. Never had to deal wit this kind of issue. The entire front of my car was soaked. literally a puddle at the foot pedals on the driver side. I Dont have a garage just a drive way. After wet vacuuming the car I still have no power or lights. Except now when I put the key in ignition it turns but nothing happens just a constant click or ticking noise coming from the fuse box under the hood on the right side of the engine. I figured maybe to use my portable jumper to charge the car up. I have a bluetooth obd2 already installed so that I can get a read but the car give me no power at all... please help... my car is only 10 months old I am the second owner and Its PAID FOR 10k CASH. Keeps my business afloat and my bills paid.

Never tested this but I thought this cars will close windows and sunroof when sense rain/water.

Me too reason I made the decision to purchase for cash from the dealer after an old lady ran her f350 into my 2014 750Li BMW.

Can Bus under carper is wet, remove carpet let it dry and should work if the wires didn't corrode

I think you need to either charge your battery or if you dont have a charger remove and take to an out shop for charging.

Once everything wiring is dry connect up the battery.

Hopefully nothing permanently damaged.

I had all the windows closed and I just put a new battery I’ll check under the seats for water
