I know I already responded but dude if you just read the thread I hotlinked you'd see why.

Sorry, didn't see the link. Makes sense. This afternoon pulled the cover open on the tank and it hissed like there was pressure in the tank. Expanding air pushes fluid out the nozzle? Makes sense. So, refilled tank and left lid ajar so expanding air could escape. So far, no leaking fluid. Sounds like the check valves at the nozzles are bad as suggested. Check valves at washer nozzles? Who knew? Could they make things any more complicated? Friggin' Germans.

I had what I though were leaky check valves at the nozzles but clearing the cap vent seems to have stopped the leaking...

I am not reposting that info again on the screen on the reseviour tank that allows the bucket to vent that every tech and homeowner throws away.

No need - not all configurations have that screen - mine never did. Just a pin hole in the main hinged cap (that became blocked with dried detergent particles).

*edit* See here - part #5 is missing (greyed out).

I recently ordered a replacement cap because I lost mine. No vent of any kind in the new one, nor any I remember in the old. I've left the cap loose for the last couple days and no fluid loss, so I think I'll drill a small hole in the cap. Problem solved. Maybe.

I think what StephenVA was saying was that there is the small screen inset missing, which allows the cap to vent properly. But a pin hole will do the same thing.

Lord (and BMW) only knows why some markets get a screen but no vent and others are the other way around.

Drilled a small hole in the cap. Problem solved!

This is the stuff you can't make up. Drill a hole - cost $0. Replace the screen/spacer $6.62 (ECS)
