Water behind the taillights

[Goli225]

Hello, I have a problem.  I have water behind the taillights, always after rain or washing.  What could be the problem?  There is about half a liter of water above the ventilation box and it is flowing into my trunk.  Is the seal faulty?  Thanks for the answers.  Berlingo Multispace 2013 B9 (Sorry - translator)

Hello, please only use English on the forum.

Yeah, I could have used Google translate too. But it's an English-language-only forum.

If we went to the bother of translating for everyone who posted in another language, then it stops people just doing it themselves - which is what they are supposed to do in the first place.

You'll notice the OP put the title in English and then didn't bother with the main post.

Sorry, I repaired it.

Hi there @Goli225, no problem! Thank you for translating - it helps everyone - as doing it yourself once, saves others having to do it each time someone finds the post and tries to read it.

Ok, there is also a rubber seal between the lamp holder unit which can unclip from the lens, and the lens itself. The seal on the lamp holder is attached to it. The water must be getting past the lamp holder seal, to get inside the lens itself. Or there is a crack in the plastic somewhere.

There is also a seal around the plug which connects the light to the car or van, this could let water in as there are holes inside the sealed area:
