Leaking when refilling washer bottle

[ac427]

I thought i would top up my washer bottle only to find the some of the water dripping from under the car.

Do the washer fluid tanks split after when older like the expansion tanks do?

Is it possible to replace the tank from the inside the wheel arch?

It can be the grommets of the pump/pumps. There are also o-rings on the hoses that connect to the headlamp washers if you have those.

Thank you. I think there is still quite a lot of fluid in there. I think link must be half way up the tank.

Are any of the O-rings and gromments near the middle or top of the bottle?

Towards the bottom. At like 70% down there.

this image shows one side, cars with headlight washers have another on the other side, you can see the tab for the pump, those insert in grommets.

but more likely it will be the orings

remove the lower half of the passanger side wheel well and you will see where it leaks. 6 screws to remove, you don't even have to remove the wheel, just turn it to make some space to have access

This happened to me some years back. There was some sort of retaining clip/screw on the bumper , can’t remember exactly what it was holding. But the tip of the screw had punctured my reservoir… probably from hitting a speed bump and somehow getting the screw to penetrate…

I had to pull the front bumper and the passenger front fender liner if I remember correctly

If I recall, the filler neck is also "sealed" to the reservoir with an o-ring; could leak there too maybe? Mine leaked at the pump grommet years ago.

If the fluid loss is immediate it could also be a tear in the fill hose itself. I had to replace that on my M5 last year, along with leaking gaskets.
