Washer fluid leaking - E39, 530-2002 - BMW Forum

My water fluid is leaking only when the tank is full.

If I fill half of a little more, it is ok, but if I keep filling with water, it reaches a stage where it will start leaking from a position almost below the front passenger seat. Therefore I am ending of having only half tank or a little more!!!

Is it leaking from the tank, or from a certain joint with the system?

Any hints?

Thats hard to say, best thing is to remove the washer bottle and fill it, then you will see.

Rashid, you and I must be driving the same car. My car was leaking windshield washer fluid. It was the windshield washer pump. It is located inside the wheel housing of the front passenger tire. Remove your front passenger tire and the wheel housing and it's all in there: the pump, hoses, washers, reservoir. From there you should figure out what's leaking.

Thanks for the information.

I have taken the car to a mechanic, who has clarified that it is normal when the tank is overfilled, the extra water will come from the inside the wheel housing, but not from the top nick. It seams, that the bottom end of filling nick is not sealed on the water tank & therefore the extra water should come from there.

Sill need to check the washer pump & hoses becuase i feel the water is finishing fast.

Can any one confirm / clarify the above??

Rashid, I had the same problem. Washer bottle had a crack in the neck of the bottle. All the water above the crack would just seep out and form puddle on floor. Either buy new bottle, try and repair crack or live with it as I did.

I've been told that it is design problem!!!

repaired the leak on the tank but two weeks later, “washer fluid low” message appeared, though the water is more than half. Sometimes this message will go by itself & sometimes by filling more water. What is likely the cause of this message?

It has to be the sensor thats playing up.

Rashid, Worked on mine today and yes there is a overflow at top of tank. In order to get to the tank the wheel well must be removed. It isnt very hard just plan on an hour or so to get it done . There are several points at which it could leak,there is a sensor mounted down low and there is the pump itself which slips down into a rubber collar, or a crack in the tank.Good luck..
