Washer bottle repair

[Crossley Family <crossley@northwest.com>]

Has anybody been able to successfully repair the plastic washer bottle
that Audi uses.  Seems that my '91 200q has joined my wife's '93 90q in
its ability to not hold its water.  The '91 bottle has developed a crack
on the nozzle that receives the level sensor and I would like to resolve
it without buying a new bottle or rather bottles from my friendly Audi
dealer.
TIA!
