HELP! 540i/6 reverse light sensor (archive)

[ Follow Ups ] [ 5-series (E34) Message Board ] [ Msg. Board FAQ ]

My 540i/6 has had a plethora of electronic problems. First the washer fluid pump quit working. Second, the right rear mirror quit tilting in reverse (mirror switch is selected to left) and backup lights are intermittent. They all happen to be on the same fuse. No luck with old fuse or new fuse. I confirmed that the mirror tilt and backup lights would fail to work at the same time. AH, reverse sensor. Bentley was very vague on where the senor was located. I found an electrical sensor in the tranny, left side, next to the tranny fluid check point. Connections looked good. Can anyone confirm that this is the proper sensor. Also bentley said to check the tranny fluid before I took the car off the rack, Why ???. Any ideas on the washer pump? It makes no noise when I try to use it, and fluid is full. I checked the connection, looked good. I'll guess the next step is to buy a new pump.

Thanks for any help !!
