X3 2012 - Acceleration Hesitation

I purchased my X3 in Feb 2012. I noticed some acceleration hesitation issues & noted that Consumer Reports mentioned it in their evauation. I googled the issue & found Bimmerfest, where I learned about the software fix. I contacted BMW who claims that the software fix for this problem is already in the model I purchased. I don't know how bad it was before, so I don't have a means of comparison. I would like to know if others are still experiencing this problem after the "fix"? If so, have you had any luck in finding a resolution? If no one is experiencing this issue, maybe I am expecting too much.

There has been plenty of discussion about this programming fault.

BMW corrected it with a TSB... search the forum.

I had previously checked what was out there on this issue. My X3 is suppossed to have the software fix already. I am curious if those who have post "fix" X3's still find this problem. To me, it does still exhibit some hesitation in certain circumstances, which can be a bit annoying. I had previous BMW models without coming across this. It just surprised me to encounter it.

I still experience it, including a revving in a low gear from a stop until the car reaches what I believe to be an excessive RPM level before it changes gears. It's erratic in its occurrence, but it is always annoying when it happens.

Yes, I still have it in my 2011 2.8 xDrive after the software update, but only when I don't come to a complete stop, such as rolling up to a red light and it turns green before I come to a complete stop.

Last week I started to turn down a street but found it closed, I turned the wheel and tried to give it gas to get going back on the original road.... I pressed the gas and nothing happened... for what seemed an eternity... I'm sure it was just a split second. My 1 series would never do this. Never experienced this with Z3's, e39's, e46, or e82 models.

I also find that pushing the gas pedal has a much less direct connection to engine acceleration than my other BMWs. I really hope BMW comes out with a few more updates to correct this problem. This is the first BMW I've owned, out of several, that I am not totally pleased with.

Go to the previous X3 generation Forum and you will see this is the bane of the X3's existence. Major reason I did not buy a new X3.

The rolling stop acceleration/hesitation is text book screw up of the X3 AT.

I'm not sure if mine has the fix or not, but mine does have unusual acceleration from a stop. If I apply a bit of pressure to the gas pedal and then keep the pressure constant, it accelerates very conservatively and smooth... but if I apply a slightly increasing amount of pressure it launches off the line very aggressively. I've driven a lot of different cars and never seen one behave this way.

I assumed this was intentional, to provide an economical start or a quick start... but it seems unnatural. I've gotten used to it, but maybe it is a bug after all?
