One problem related to rear window wiper washer has been reported for the 2006 BMW 5 Series. The most recently reported issues are listed below.
The panoramic sunroof on e60 BMW wagons has a faulty design of the drains which re-directs water into the rear of the car (spare tire area) causing multiple electrical components to fail while driving: lights, windshield wipers, door locks, speedometer, etc. In my case, the failure occurred twice in a period of 18 months. The dealer and BMW north America repaired the car at owners' expense although an extended warranty was in force. There has been a technical service bulletin issued by BMW but the dealer does not acknowledge the flaw and refers to the failure being caused by 'environmental influences'.
