I have a 2007 335i coupe, and i was doing some basci checking of the car and found my battery compartment is full of water. It rained for two days straight. Well after finding this i get in my car to go home from work and all of a sudden my warning light for air bags and seatbelt are on. Is there anything related to this and the battery issue. So forums ive read say it has to do with the red plastic thing on top of the battery getting wet. If anyone could help that'd be great. Thanks.
