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

Cmassey3 · 10-31-2021, 01:31 PM

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?
