There was no date information for this fix, sorry. Just the TSB# was on the invoice.

I spent an entire day running errands in the X3 and the quietness is amazing. I never realized how much I hated that whistle noise. The inside of the cabin isn't Lexus vault like queit, but that's ok for me, I don't mind the road noise. It was just a constant whistle that this fix eliminated.
