E92 M3 is deluging washer fluid from around the tip of the right front bumper

I've been researching a few threads on this after finding my M3 triggering the low washer fluid warning every 48 hours after adding a full bottle of washer fluid.

I've tried the idea of taking out the headlight washer fuse, but I don't think this stops the fluid flow to the leak.

I also haven't seen a consensus on if this is a front bumper removal or a right front fender liner removal to address the forward leak.

I've got a picture of the drip point but I can't tell if it's the hose to the washer pump or the pump tip itself, what's the best way to diagnose it? I kind of want to find the source before I rip everything apart because I don't have a garage where I can leave everything apart for a week while waiting on a part.

Can the fluid be shut off from reaching the headlight washer?

i would at leat remove the fender liner so u can see the source of the leak, if u still cant see anything remove the bumper. its not that difficult to remove and reinstall if u have to order parts.

I've preemptively ordered a replacement headlight washer since the leak is definitely on the forward side of the passenger wheel well. I'll have to source a jack so I can get the wheel off and access the inner fender liner.

Issue has returned unfortunately, shop fixed it last time by reinstalling the bumper. Would this point to a blown O-ring in the passenger washer nozzle?

It's back with a vengeance. This'll be the 3rd time I'm embarking on a fix. Seems to be like the headlight washer nozzle gets stuck open and flows out at maybe a tablespoon of liquid a minute. My main washer motor is no longer engaging, so this needs a complete overhaul.

Likely broken washer pump or hose. It's a fairly common problem.

I had this years ago and it was the rubber grommet on the pump. Pop off the wheel and fender liner and you should be able to see what exactly or where it’s leaking.
