Window washer leak on 2007 Volkswagen Passat

Is it possible to repair leaking window washer tank without having to remove it-big job to get at the tank!

1 make sure it is the tank leaking. Sometimes the pump, often mounted in the bottom of the tank, is what is leaking.
2. If it is the tank, the kind of plastic used in these tanks rarely accepts glue or sealer, and usually starts leaking again shortly. Replace the tank.
Thanks John,no easy fix then,regards,Con.
