After years of changing light bulbs and cleaning & corrosion protecting the electrical contacts on my X5, I have found the real culprit for all of these problems. I have found that I have an internal water leak coming from the sunroof and dripping right over the electrical fuses on the right-real panel . Somehow the water is not properly draining and is getting into the inner steel framing. The water and moisture collects on this cavity and makes havoc of all the electrical contacts and of course it also corrodes the rear lights and the brake lights. I flushed the two roof drains and they appear to not be clogged, but somehow when I test it for water intrusion the water still drips right over the electrical fuse box. Has anyone tried to solve this problem?
I truly believe this should be a major recall issued due to its nature and the fact that everyone seems to be having this so called “ Moisture and Corrosion Issue” with their tail lights.
At first there is moisture then there is lots of visible water…..take a look!
