It is best to look for water leaks when everything is dry. First is the door seal or door, damaged in anyway? I have seen the seat belt having damaged the door seal on many vehicles. Do the doors close flush with body? Ensure the door seal makes good and uniform contact with the door (particularly important if the vehicle has been involved in an accident. You may need to pull back carpets pull back the carpets and sit inside the car (you may need a flashlight) and get a friend with a garden hose to spray water around the door jams to determine if the water is entering the doorway. Then spray water around the rear windscreen moving around the circumference of the windscreen. Look around the windscreen area and look up from the floor mat area (as best you can) to determine if water is leaking in around the windscreen seal. Is there any rust around the windscreen area or body work? If you have a sun roof there is a drain tube at each corner of the roof to channel away water. A blocked drain may cause water to fall from the sunroof area Water can also come up through the floor pan as you drive through water on the road, if any rubber bung or “seam sealer” has been disturbed or is missing.
My Audi allroad 2001 has water in passenger side seat area and drain to rear passenger side floor area. The clogged drains have caused trans to go into limp, home mode. Electrical harness must have gotten wet. Hard to start and or even go into drive. Car bucked a bit then settled down. Seems to stay in 3 rd gear. What needs to be replaced and or dried out and cleaned. Is ther a diagram of where drains are and what to do info. This just happened so I am beyond the class action suit date of July 20th or so to get in on the claims. Any ideas out there.
