Our TT does the same thing. It won't leak when the car is off, but if you drive it, it all vanishes.

I haven't figured it out yet though.

Doesn't use oil... but burns off washer fluid ?

I wonder if there's a crack/gap that leaks fluid only when disturbed by vibration.

Need to get in there and look at the tank, pumps and hoses.

I was in there once & everything looked OK...

I filled it & let it sit for 2 days & it didn't leak a drop. Then after it was driven again it rapidly dropped. I guess I will have to check again.

I thought my wife was on crack at first, but she was right it is actually disappearing.

For the time being I am just filling it with water every few days to keep the annoying low fluid indicator off. I will have to figure it out soon though since it is getting colder out.

My suspect would be that O-ring (sleeve?) that holds the pump in the tank

That's what was leaking on mine, but it was bad enough to be obvious.
