I've had an ongoing washer fluid leak & I'm finally tired of constantly refilling the tank & seeing the warning on my dash. It looks like I've found the cause. Any recommendations or procedures to stop this leak? You can see in the pictures where the leak is coming from. Any help would be much appreciated, thanks.

Thanks a bunch! That seems quite logical. Where can this be ordered from?

The grommet doesn't look too bad, could it be the pump?

maybe the grommets looks fine, but can't assure that, cause when you put the pump, its squeezes the grommet from inside,,

Im not sure about the pump itself, but usually these grommets cause leaks once a while....

Well.. Fingers crossed, I refitted it back onto the grommet and it's no longer leaking. Maybe it was just loose? Thanks for your help ZAYED.

Update on this? I've got the same issue and as Zayed pointed out, it's either the grommet(s) or pump unit itself. Not a huge deal, you can order replacements for both grommets and washer pump units (there are two, one for the headlight washers) from azautohaus.com or BMAparts.com.

Fully agree,

replace the pump with grommets are best to go, avoid any kind of headache....

I'm currently in LA, but will report back on Friday when I return. Seemed ok before I left, but can't guarantee success. Is yours leaking from the same spot?

Ages ago mine sprung a leak from the exact same spot. I replaced the grommet with the part from AutohausAZ and it has never leaked since.

I typically R&R the tank for better access when changing spark plugs. I believe that is what caused my leak.

Well, I'm seeing the lower washer illumination on my cluster again. Looks like I'll be ordering the grommet today.

Ordered both grommets from AutoHausAZ. After replacing them, I can confidently say my reservoir is no longer leaking
