Hello, all! Bummer Bimmer decision point. I found water in driver's footwell after heavy storm. I live in San Antonio, TX and I parked my car on driveway facing toward street. The driveway has a slight 10 -15 degree downward slope. I took the car to a local BIMRS-certified shop and they performed various leak tests and conducted SIB 54 12 09 which consisted of applying top repellant 83 19 2 339 673 and Convertible Top Filler Foam (to make seals "fatter") 51 76 4 868 868. The advisor said they "believe that replacing all of the top seals would be the the best course of action to prevent water from entering the vehicle." He stated parts would be about $7,000 (their price) + labor. I looked at the rubber seal at the front and it does look dry and rough. The advisor also suggested that I consider getting a trade in on a new or newer model. Other than the issue of water coming in, the car works fine and only has 73,7420 miles on it. I would rather spend a couple of thousand dollars instead of car payments for 5 years. Can anyone provide info on SIB 54 12 09? I was not able to find it online. I reviewed all the posts on these forums, e46 Fanatics forums, and bart of Bavauto.com E93 tech blogs and was unable to find anything that addressed this issue thus far. Has anyone experienced this issue and have any solutions? Also, if I were to buy the parts at a lower price, which I did find on various sites, is this a workable solution and does anybody have installation instructions? Thanks!
