Porsche Computer Under The Seat Destroyed By Water Leak - describes multiple Porsche owners (not just Boxsters) with this problem. I've had it twice. Google Porsche water under the seat for hundreds of complaints. Very expensive, but autoins. may cover it.
Porsche Boxster has 2 small water drain tubes under the soft top which allow water to go under the car. If they are clogged, water is running inside the car on carpets. There is a very sensitive control unit under the seat of the driver. It's alarm connected with the horn, electric windows etc. If it gets wet, you have a one thousand dollar repair because you have to replace this unit which is impossible without special Porsche diagnostic tool.
