As the OP of this thread, I need to revisit it...
Same subject, different problem, but still undiscovered..
Found a puddle of WW fluid under my X5 yesterday morning...
Took to my friendly Indy buddy, (11 degree outside temp and no heated garage = No DIY)Replaced the pump that looked like it was leaking.
Drove her home, and said good night
Woke this AM and there is a BIGGER puddle under the X.
Took it back to Indy (it was 4PM so we were a bit rushed), but the pump was not leaking.
There seems to be a leak somewhere heading towards the headlight washer on the PASS Side, but darned if either of us could find it.. we found a tiny puddle on the frame rail. But that's about it...

Any one got any ideas...??
