Water leakage into cabin of Mercedes 2002 C240

Last week I parked my car facing up a slight (~10°) hill in the rain. After the rain there was ~1/2 liter of water on the floor, and more drained out from under the driver's side dash when the car began to move. I checked for leaves or other blockage to drain holes under the hood, but everything looks clean. Mercedes dealer reports there is no service bulletin about this problem. Does anyone have any insight into this or the solution (never park outside in the rain, right)?

2005 mercedes benz c240

I have 2005 e320. I had water coming through the headliner after a good rain. I thought the seal on the sunroof had possibly been compromised, I took it into the dealership only to be told that leaves get washed down into the body of the car and block the body drain holes. I was charged to have the right front wheel and wheel well cover removed. They ran a coat hanger or long screw driver up into the drain holes under the wheel well and flushed it with water. I watched as this was done. Leaves did indeed come out of the body of the car. When these holes get blocked, the water backs up into the car and comes through the panel and sometimes out of the passenger door frame. This has caused electrical problems with the vehicle as things are getting wet. This is a terrible design flaw and should be recalled for a fix! In the meantime, I'll try to keep my car covered so that no leaves fall down along the windshield and subsequently get washed down into the body. For a Mercedes one sure wouldn't expect this type of problem without the manufacturer stepping up to make it right!
