Leaking Washer Bottle

[ancelot1]

As you can see in the picture water is running down the outside of the washer bottle on my Audi 100. It looks like it is coming from around what I guess is a sensor fitted at the bottom of the bottle.

I can wiggle it in but I am not sure if I pull hard on it if it will come out so I could try resealing it with something, or if I will just break it and make things worse. Would I be better off trying to seal it in place

Any advice gratefully received.
