I have this problem , it keeps wetting my air bag sensor anoying , if u look under ur sill theres rubber plugs if u can c any missing , jet washing underneath doesnt help . I pulled the carpets up which if ur carfull the plastics around the bottom off door frame unclip easy . Clean the mess block the holes . Go scrap yard 4 more rubber plugs , i did , it will sort it . I took my battery off . U dnt want to trigger any airbags whilst under that seat . Let me no how u get on .
