Even though there's an explanation why this is happening, it doesn't make it acceptable IMHO. I can live with mediocre navigation/computer software (idrive) and other stuff like that, but when it comes to mechanical issues it should be superb. Getting a 'slam' when you're coming to a stop is bull crap and I certainly don't expect it from a car as expensive as a 550i. You don't get it in the 530i, 540i and certainly not in Jap cars that I've been in 
The software fix doesn't fix it so it sounds like we've got to live with it...for now..
Still, despite this problem I love my 550i

Sport mode or normal?
Ok, now I must show my ignorance. I recently acquired a 07 550i 6 speed manual. I have not noticed a sport mode button. I had one on my E39 M5 but not on the 550i. Is this just a Steptronic thing or have I yet to discover a pleasant option?

From yr past cars you owned a MB 320. THEN after a 2 BMWs.
What is yr comments between the 2 brands ????

In short, I wouldn't bag one against the other as they're both great cars just targetted at different driving styles. If I was more conservative in my driving then I'd go for the E-class. However, from what I've heard the new MB E550 offers a superb blend of sports & comfort via it's improved dynamic suspension. It certainly has far more grunt then the 550i, faster in the straights and grips more in the turns. Have not driven one yet to confirm this... oh and I think it's cheaper too!
Speaking to some friends and after reading some motor mags comparisons, I think you'd be choosing BMW between the 2.0lt - 3.5lt (twin turbo!!) mark, but then you'd might want to consider the MB V8 E550 over the BMW 550i.

My Ride: 2008 Sapphire Black on Black M5 - loaded sans soft close doors
Mine did it a lot at first and now has stopped. So it sort of goes away... I am however getting a rough 2-3 shift (car starts out in 2nd normally) when the trans is cold. That I swear is new

The Sport Mode is referring to cars with Steptronic. However, cars that are equipped with SMG have the sport button. Hope this clears everything up.

I know my car is brand new but whenever I come to either an abrupt stop or come to a light the downshifts aren't smooth. In fact, tonight it felt like the car wanted to stall out. I had the same problem on my 540i as well. Do you think this could be a software issue? Has anyone had this problem before? Thanks!

You did not state the number of miles driven. I have ~9000 miles on my 07 550i (June Del). It originally had a similar issue when approaching a stop the transmission would downshift erratically. That problem has disappeared as my mileage increased. It was around 5000 miles where it stopped. I figure it must have been breaking in. I had no software updates till just last week (V24.02) so it was not software related. My suggestion is to give it some time. If it does not work its way out then take in it.
