[s-cars] leaking windshield washer tank?

[Lee Levitt]

My wife's '96 A6 is going through a lot of windshield washer fluid and I
suspect a leak somewhere. She ran the windshield washers in the garage and I
did not see any obvious leakage. 

 

With the ignition and headlights on but the engine off, the headlamp washers
did not pop out. I'm ASSuming that the engine must be running for them to
engage and wash the headlamps. In any event, I did not see any leakage along
the hoses running to the headlamps.or anywhere else.

 

What else should I be checking?

Thanks,
