Windshield Washer Fluid Leak

I have a 2009 335i. About a month ago I had a dealer fill my washer fluid because the warning light came on. Since it's summer, I haven't really had to use it much since then, however when I did try to use it, nothing came out. Then the next day I got the warning that I was low, again. Obviously there was a leak somewhere. I had ordered some OEM fluid by that point, so I filled it back up to see if I could determine where the leak was coming from. There was no immediate leak after filling, so I tried using it again and after I hit the trigger twice, it starts pouring out by the front passenger side tire area. Is this a pump issue?

Very likely. You can DIY this project. It does require removing the front wheel and fender liner but it can be done. Get a new pump, grommet, and strainer while you are at it.

Bummer. Thanks for the quick response! I'll have to look at some videos on lunch. In your opinion, is this a fairly straight forward repair? I'm not super handy, but I did recently replace the spark plugs and ignition coils by watching a video and using a very methodical approach. Also, do you know if any special tools are needed? (Like the spark plug adapter I didn't realize I needed when I started that project)

It is a bit hard to get to but doable. Not sure if yours also has the headlight washer (my X5 does, plus rear window washer) but if it does I would strongly suggest you replace both pumps at the same time. The pumps are about $68 but the labor to get in there is multiple steps.

I just replaced my windshield washer fluid pump last week after it failed. It is a straightforward repair, but you will need to jack up the car and remove the front wheel. Removing the fender liner isn't that complicated. You will need 8 mm and 10 mm sockets. There is a great DIY video on Youtube for the repair with clear step by step directions.

There is a small strainer that fits underwear the pump were it is inserted in the reservoir. Some owners state that their strainer was clogged. I wasn't sure, so I ordered a replacement strainer. Got the pump and strainer from ECS tuning. I removed the reservoir and unclipped the fluid supply hose. Somehow I nicked the line removing it from the reservoir. So be careful if you use a screwdriver to lever the clip back to remove the hose. I had to drain the line, dry it and use some RTV sealant to stop the leak from the hose. It's a $35 part if you have to replace it, which you shouldn't need to do.

This happened to me six months ago. It cost about $150 (parts/labor) to replace the pump at an independent shop. As you already know, replacement requires removal of the wheel and fender liner. Make sure the grommet is replaced as well.

This is the same level of difficulty as spark plugs and coils.

Get the Febi brand pump from pelican parts and save yourself some money.

Seems like a fairly common failure. I had mine fixed under maxcare warranty with a few other things when my water pump finally failed.

Yeah, I replaced my pump and gasket a LONG time ago, when your leaks persist, and I think they will, look at the real culprit the headlight washer nozzles, it fixed the leak finally on ONE side, now the other side is leaking, they clog and it pisses out the back of them - easier to get to (than the pump on tank) but OEM nozzles are expensive, I am going to try silicone sealant and a tighter connection via a tie-rap for the other side before I pop for a new nozzle YMMV but I doubt it.
