Hmm, thats happend two weeks ago. I just loosing washer fluid, but i dont know, where from.

'99 2.8 quattro

 

Mine leaks from the headlight washers.

 

But leaking, when i do not use washer.

 

It commonly breaks off at the fitting on the washer pumps, take the belly pan off and you can see both the headlight washer pump and windshild pump. It will be either that or a plastic connector fitting.

 

It is fairly common for the headlight washer pump to crack and leak. Poor design of the pump body. The quality of the replacement pump is better. Search on AudiWorld for the techarticle on how to replace that pump. About a $20 part and all you need are some common tools and you can DIY.

 

my 99 a6 was also leaking washer fluid,so i checked it out and itwas only a loose clamp,so i bought some new clamps and the problem was gone

 

where did u found it?

Hmm, i cant find anything, about how to repar pump at http://www.audiworld.com/tech/
