Windshield washer fluid light...?

A few weeks ago the light on the dash came up, I checked the tank and sure enough it was empty so on my next gas trip I filled it up... the light went off and that was that.

2 days ago I was on a roadtrip and the light came on again so I stopped at the next rest stop and filled it up, but the light stayed on. I thought it was strange but I had washer fluid so I didn't care. Yesterday when it was time to come home I ran out of fluid halfway through my trip, but I only sprayed maybe 20 times the entire trip?

My light is still on and I have no washer fluid... it seems like it stays in the reservoir but when I start using it the amount of washer fluid decreases much more rapidly.

The tank itself isn't leaking I checked, so I'm stumped... any thoughts?

Fill it up with water, park it, and check underneath in the morning to rule out leaks.

it's leaking somewhere. washer fluid doesn't magically disappear into thin air. mine is currently leaking as well. in my case, i think it is the pump itself that is the culprit.

I know it sounds stupid, but you didn't leave the cap off after refilling did you? Mine evaporated after topping up and leaving the cap off! Ooops!

I will do that to be absolutely sure.

I'm pretty sure it's something else too. It doesn't leak when parked, only when being used. And the stream of fluid on the left is SLIGHTLY weaker than on the right, so I'm thinking some gets lost somewhere between the reservoir and where it exits to hit the windshield. Could be the pump or one of the hoses?

Anyone else have any experience with this acting up?

If you have the cold weather package (heated seats, headlight washers, ski sack etc.) there could be a leak within the headlight washers. It could be the headlight washer pump itself, or where the spray nozzle cover attaches to the pump. My pumps went bad a long time ago and I had them replaced under warranty. You should def. fill up the tank, spray, and check for leaks regardless. These diagrams from realoem may help-http://www.realoem.com/bmw/partgrp.d...25&hg=61&fg=45

In that case, no I don't have the cold weather package. I was wondering why my other BMWs have heated seats and this one doesn't, thanks for clarifying. So if I don't have the headlight washer pump could it be another pump? I'm thinking that's what it is since the tank itself doesn't seem to be leaking.

It is only held in with 1 bolt. Might as well unbolt it, and unclip the sensors connectors and pump connectors. Then just look around the reservoir, shake the fluid around, etc... Check around where the pump and sensors go in.

mine was leaking a few days ago. took the tank out, sure enough one of the hoses was loose connecting to the pump. its not hard to do at all, just un-bolt the one bolt and its pretty much a no brainer from there....

mine goes through it insanely fast when i use it.. i remember buying fluid for other cars and i would pour 1/3 of the bottle in.. e46.. you just turn the bottle upside down and let it go.. then a few weeks later if you use it the light comes on again.. i mean, i could care less if it sprays it on my headlights.. but it does.. i want some mini wiperblades on them.. volvo style, that's pimp...



pic related.. but horribly implemented.

i believe that the washer fluid pump seals tend to die..mine did and it started leaking through the weep hole on the pump.

Yeah, check the seals by the pump, it's probably leaking. Is there a puddle under the car when you park?

Common problem. Replace the washer fluid pump itself. It is only a $40 part from Bavauto.com. It takes 5-10 minutes to replace.

No there's no puddle I think it only leaks when I actually use it (it's been filled and stayed filled for a few weeks, but when I use it it seems to drain extremely fast)

I think he is correct, picked a washer fluid pump up at the dealer ($28.00) 10 min later, no problem.
