I replaced our windshield wipers with the Rain-X latitude ones, can't recall the sizes though. Our 2007 X3 3.0si was also leaking out of one of the washer pumps. I purchased the washer grommet from the local dealer, cost me like ~$5.00. I also replaced the washer pump but I didn't get it from the dealer since they were charging $80.00 for one. I ended up ordering one from Auto Parts Warehouse:
Washer Pump AutoTrust Gold Washer Pump AutoTrust Gold
Price: $ 28.65
Part #: WREPM371501ATG
when I connected the pump, at first I thought I got the wrong once since no water was coming out. It took a few minutes because it was the pump for the rear window. Also, I doubt the original pump was defective yet I still purchased a new one since it wasn't that expensive. No more leaks though!
I changed the part out sometime during November of last year and the vehicle had approximately 88,125 Miles.
