Wiper Fluid Slow Leak

I've got a SLOW leak but there isn't a trail showing where it could be coming from...the only thing I see is a blue residue on the pump. Could that be the cause? Btw, it still pumps so it's not dead...just leaky?

Thanks

Had the same thing on my 06.Eventually it started leaking to the ground.
Picked up a new pump at dealer for $50. and installed it myself (3 min.job).

+1 one of the few VERY easy DIY jobs on an X3.

Same thing here. Got a pump off e-bay for $15, workin great!
