When was your 09 built? According to the SIB it's really for the 08 while the "Delayed Up_shift in Hill Program" SIB is for up to 04/27/09. Maybe your dealer isn't lying to you. Your car could possible have the latest update which simply means that it doesn't solve what you are experiencing.

I'm guessing that you are experiencing what I am (even with the updates done). Pretty disappointing. I also think that some of the other posters in this thread might have been experiencing something worse that made them feel like the SIB really worked OR maybe they just drive more aggressively all the time. I think it's the trying to start smoothly with a light foot that really throws the transmission/throttle response off. (It's pretty much this and the long wait for the rear view camera to be useable that makes me regret getting my X5).

My dealer told me it was built in mid-july....i know what you mean but thats not my case for sure, i got a heavy foot...im the type of guy who peels out from park like a jerkoff.

yea and the rear view camera is bullshit.
