I am having a problem with my 2000 Mercedes S500. We had a huge rainstorm 2 weeks ago and this caused water flow in my front passenger seàt. Now my fuel gauge doesn't work, lights turn on and off o n the inside of the car, and when I turn the car off the brake light and when park lights stay on.

Hi, my name is***** is a common problem on the S class. You will need to replace the rear fuse box and signal acquisition module located underneath the right rear seat cushion. Disconnect the negative battery cable before replacing the fuse box and module. You can purchase used ones on ebay. You will also need to clean the cowl drain at the air intake vent at the right side below the windshield. That's why the inside of the car flooded.
