Here you go: When your Washer Fluid Reservoir begins to leak on the garage floor.
Quick visual inspection will tell you which pump is the leaker: Fluid stains and the level where the fluid stops leaking. Pumps leak at the seal to the reservoir and they leak internally as their guts wear out. Cheapo ones have a short life, OE or OE aftermarket last years. Lines break as age and owner/tech abuse take their toll. Mine own X5 had three sets of pumps installed under warranty. Still leaked as they never replace the cracked seal for the windshield pump. You think someone would have noticed but their are positioned against the firewall, so without a mirror and a flashlight....

Instructions:

X5 pumps
two small ones - Front and rear windows - Image #4 PN 67128362154
Big guy - headlamp washers if equipped (Blocked if NO) - Image #11

Once again
Loosen bucket,Pull pumps, remove and wash and clean bucket with 1/4 cup ammonia to 1 gal water, scrub housing with Comet, rinse with Dawn Dish Detergent.
Replace BOTH small pumps with OE aftermarket pumps. Washer Pump PN

Replace two small pump seals: Washer Pump Strainer & Gasket PN61667006063

Replace LARGE pump seal with PN61 67 8 374 382

Alignment tool for nozzles: Washer Nozzle Adjuster Tool https://www.ecstuning.com/b-bav-auto...r/wnatool~bav/

Double check your hood nozzles to ensure they flow cleanly, right pattern, and are heating otherwise they freeze in the cold and crack.

Install if missing Washer Fluid Bottle Strainer PN61661365848
https://www.ecstuning.com/b-genuine-...r/61661365848/
This part stops the pressure build up and having to drill a hole in the cap, which in turn will leak/sweat every time you go around a corner.

TIP: Mark each connector as your remove it as having the rear washer go off every time you want the windshield washed gets old real quick.

DO NOT break the plastic tubing, Twist to release the pumps to the lines. If COLD outside, heat first.
