I recently purchased my first car, a 2000 328i. I love it and couldn't be happier, other than all the modifications i have planned. I've been experiencing problems with my wipers shutting off arbitrarily. I'm not sure if its the wiper motors, which i dont think it is as they sound fine. I believe the windshield was replaced once so it may be the rain sensor, before i take it to get looked at I was wondering if there is a known problem with these or not.
