Hello i am new to the website and Mercedes so any help will be greatly appreciated. Yesterday i stopped by the local laser car was and water started pouring in by the bottom of my doors underneath the dash area. It was very odd considering i had just went to same carwash and had no problems. Anyways i try and dry some of it up and go about my day. 2 miles down the road my trans just slipped out of no were. I start to panic and try to bust a U-turn to go back home and it would not shift into reverse to finish my U-turn, so i cut car off and try to crank back up and nothing happens but start error messge. Out of no were after 30 mins of trying car cranks and gets me to my house in 1st gear. I wake up the following morning and it cranks no problem and it still will not shift out of park so i use the emergency shifter and i drive around the block car shifts threw all gears fine but no reverse light. All other lights work fine. Any help would be greatly apprecited!
