yea i had that... it took me a day, but i took it all apart, pulled it away from that sticky black stuff, then disassmbled the bottom clear lens part which was leaking... this was hard because it was sealed with hot glue or sum clear sticky stuff, so i poured hot (not boiling) water over it and kept pulling it out, took ages but eventually it came out. Then cleaned it up and re sealed everything with sealicon. Its being fine ever since!!! for me it needed to be done because water was actually leaking into the boot of my car which in the long run would of caused rust.
