Washer fluid reservoir leak - they all do it!

I know this issue has been discussed in this forum in the past, but I need some help. 06 S55 AMG. I placed the small tube at the reservoir connection as suggested. But this apparently is not the sourse of the leak. The reservoir completely empties below the reservoir connection so the leak must be below that. Is there another know cause for this leak? I'll try anything before going to the dealer. Thanks.

When you say they fail where the pumps mount do you mean that the pump seal fails? Does this require replacement of the pumps? Thanks.

I think you need to change the o-ring in the quick connector at the base of the reservoir (when its empty!).

I bought 1000 assorted nitrile o-rings when I bought my S600, and they've been one of the better no-brain investments.
