Fellas this has to be my worst Mercedes week of all time 😢😢 last night we had a pretty heavy rain in Cleveland. I had the Mercedes parked on a slight incline. Around midnight the neighbor called and said that my car lights were on and she was making a hum noise. I went outside and disconnected the battery. This am I went back out and the drivers floor was soaked. After soaking it up for 10 mins with a towel, I decided to lift the carpet. Wow there was at least 8 ounces, for which I grabbed the shop vac. Now the wiring is runs on the side of the frame by your left foot, and not directly on the floor, but im sure that it must have gotten wet. Does the car suffer ECM damage when this happens? Iím going to take a hair dryer out to try to dry up the area. Please tell me this is not a computer death on the W202.... any insight will be appreciated 😇😇😇😇
As George said. You have a w203 - this forum
Do a search in that forum or even the w202, w210 and w163 forum with the term "water in footwell" or similar.
Drainage systems are pretty much similar in all the models across the board.
You find more useful info and solutions.
btw, you're going to need get ALL that moisture out under those HD carpets. Water/moisture gets trapped under there - been there, done it (other members too). Hairdryer positioned under the heavy carpeting at low heat and speed left for and evening might do it, depending on how much water you can get out. And a disinfectant too on the carpets to get rid of the mold mildew smell buildup that comes later.
Most likely, water is coming thru your sunroof drainline (if you have a sunroof) that's clogged/disconnected or thru the cowel (lower windshield) - also clooged up with leaves/debris.
You'll need to check the wiring, electrical boxes under and near the water damaged area, dry it (also use electrical contact cleaner spray, if necessary) to resolve the glitching you are experiencing. It should suffice once the connections/contacts are dried.
