TD5 Water leak through seat belt mount?

As the title says noticed water driping from top belt mount, then the next day wife says air suspension light hill decent light and charging light al came on and went off. Next day battery flat, and today two gear lights, abs, suspension, hill decent,sbs, charge and various other lights came on and now battery flat again. Could water have got into electrics somewhere?.we have owned it for two years and this is the first problem.

The water through the seatbelt mount could either be water leaking through the sunroof, or the roof bar mount.
Sounds like you could have water issues elsewhere.
