I stand corrected. You assumed I didn't read through the forums. I did search through the forums and I tried most other ideas people suggested about the leaks as well as what to do when your key fob is screwed up and won't work. I visited the drain fix and tried that. With no luck. Tried all the ideas about getting the key fob to work too with no luck. Kept wondering how water was getting inside standing in the floorboard and became more and more frustrated. On top of that the car was disabled for almost 2 years while waiting on a key fob that Mercedes couldn't find time to reproduce, though I paid the money to have them do it. Finally got a key fob back from Remotes and Keys after they found someone in the United States to flash the skreem and make the key from the VIN. 2 years the car sat and I couldn't even move it and I was wondering where the water came in, I checked everything I could check and then it occurred to me after I got the car running to take those windshield trim pieces off and that's when I found from my problem. But I will fall back from my 90 to 99% and say I spoke too soon, and I will say that as with most everything there's not just one answer there are several answers and there's several different things that can go wrong.. But if everything else plays out, it doesn't hurt to check this because mine is not the only car that has this problem. I know of 3 people with leaking crossfires, and that was their problem too
