I had updates done multiple times on my '08 4.8i...and sadly, for me it never helped. Honestly, I think it might have made it worse. In the past, I had transmission updates done on my E46 330cic..and it totally solved the problem. Don't know why it did not work for my E70. I do know some folks, that the update worked for...so I would for sure give it a shot. The transmission in our '07 750Li can be quite rough too at times. Our dealer said the transmission mixed with the 4.8 V8 engine gives these results. I know, total BS. Good Luck, and please let us know if the update helps you!
