Washer Fluid Tank Leaking for 2 Years
 

It leaks somewhere at the pump not the tank itself. Should I have it replaced or just top it off (cheaper solution) I top it off every month in winter and every 2 months in other season, so about 8 topoffs a year, thats about $20. Should it fix it?

The pump is a common leak point on all BMW's. I would get a new washer pump and grommet (filter), and it would be a 5 minute or less DIY repair as it is VERY simple to replace.

I had the same problem, dealership asked $250 for new resv tank, came home, start looking around, apparantly I had some thing stuck in one of the 2 motors, the motor to the rear was working hard but since the clog it kept pushing out of the small hose, all i did was took the motors out, cleaned, tighten it up anf voila, it is all set, still have the same washer fluid and I am $250 richer.

Hooray misdiagnosis!

Do we have any DIY with pictures on the forum?

i pulled the small hose off the pump and put pipe thread compound on the pump outlet and put the hose back on...its perfect.

Not that I know of, but I didn't exactly search either. But the washer solvent bottle has one 10mm screw on top, remove it. Pull the reservoir up and unplug the wires from the pump(s). (if you have 2 pumps, the smaller one to the rear is for the windshield washers) Then pull the hose off of the pump nipple. pull the pump straight up/out. Pull out and replace the push in grommet, insert the new pump, and the rest should be self explanatory. :D

All in all it is one of the easiest DIY jobs on the X5.

Check to see if it is just the grommet. I have had to, and now have to again, replace a grommet, pump may be fine.

mine was just elbow fitting
 

I had same problem. Bought the $35 washer pump and the fluid
leaked out again. Then just fooling around I saw that the elbow fitting
was bad. Took it off and just cut tip of hose off, reconnected it
and fixed!
Anybody want to buy a new washer pump??

right now my windshield washer fluid is working fine for the windshield but my headlamp washer nothing coming out. rear is working fine too. what should I check?
