hi all
i own a 2005 passat wagon and the rear off side tail light is full of water condensation
the light has been replaced by previous owner by vw for doing the same thing
how can i stop this from happening?

welcome! Have you tried pulling out the taillight to see where air or water might be getting in. Also is it still under warranty, as it could be another faulty taillight.
