frequent low windshield washer fluid
Hi all, owner x3 for 2yrs. the car runs great so far. But I ran into a weird problem. The windshield washer fluid alert will come on from time to time. I live in NorCal. There is not much chance to use it in summer. But the alert will come on fairly fast since the previous fill up. dealer torn the reservoir but found nothing. Also when I make sharp turn, the alert comes up too.
feels like the fluids just go away by itself too fast. wondering if anyone ran into the same issue? btw, if I was to top it off myself, what should I buy. thanks |

You don't say whether your fluid is actually low, or whether it's just the low level warning coming on no matter how much fluid. Assuming the fluid is actually low, you don't say how long it takes from the time you fill it until the light comes on again. The system holds about exactly a gallon. If you are losing a gallon of fluid every couple weeks or so, and your dealer could not find a leak that big, then you need a new dealer. As for filling it, just go buy the same blue stuff for any car for a couple bucks at the auto parts store. There is nothing special about washer fluid even if BMW tries to convince you that there is. Then keep track of how long it takes for your light to come on, and how much you actually used it. The fluid does not just evaporate.

first one is the fluid will really go low after a refill without being used. also from time to time, it is not really low, but the car will "think" it is low after a sharp/hard turn. I guess this is just the fluids shifting around in the tank and the sensor misread. |

I had that. Turned to be cracked tank or seal leaking around pump. Dealer did not bother to figure it out and just replaced tank with pumps under CPO.
I personally think it should be anything too complex to fix. The tank is right above right wheel behind fender. |

Thanks! I will drop off the car and tell them to look down there too. I think they took some of it apart and found nothing. But I want to have it fixed before factory warranty goes out for sure.

Had same issue. Rubber grommet of the washer pump bit the dust. Changed it and no more issues.

Mine had a slow leak, I would only notice it in the morning when getting in to the car to go to work. There would be a blue puddle near the front passenger tire. Turned out to be a bad connection between the filler tube and the reservoir. I was under warranty at the time and the dealer was right next to where I worked so I would drive it to the dealer in the morning and pick it up after work. Took three visits before they finally got it to stop leaking. BTW, it would only leak when the reservoir was full. They used silicone to seal the connection, been good now for years. |

I presume its the washer pump and/or the seal leaking, didnt think about the filler tube. But then again, I dont think it can be that because mine leaks from full to almost empty. |

Right, the key to understanding the issue I had was that it only leaked when I filled it completely and the fluid was all the way up to the cap. Anyway, get yourself a little mirror on a telescopic wand and a flashlight and poke around, you might find the issue without having to pull the inner fender out.
