The leaking windshield washer bottle (BMW 3 Series, E46 models)

If you're in your BMW 3 series, and your windshield washer fluid light comes on, what do you do? Refill the bottle of course. Then, a day goes by and the light comes back and you know haven't squirted anything on your front glass. Take a peek on your garage floor and you might see a puddle of the very same washer fluid you carefully poured into your bottle. You've got a leak!

The windshield water container, canister, bottle, whatever you wanna call it is relatively easy to take out. One bolt and and out she comes. Attached to the side is the pump, and right under the pump is a tiny strainer with a rubber o ring forming the seal.

This has actually happened to me a couple of times (living in an exceptionally hot climate might have something to do with it), and both times it has turned out to be the windshield water pump. If it's not the pump, think strainer, and lastly, suspect the bottle. Unfortunately, I haven't found any tell tale sign on how to tell which of the three it is, but I would recommend replacing the strainer and the pump at once and you'll most likely nail it.
