Yesterday, my '99 328i sat out in a huge storm: high waters, the whole deal. When I started it, I noticed that all my stereo setting were gone (like me battery had been disconected). She started up fine and drove with no issues. This morning, after a night in the garage, I can't get it to turn over. All the electrical stuff comes on, though my lights are dim.
Is it just a coincidence, or did the weather have something to do with it? Any ideas?
