I think it would be helpful for those of you who are experiencing an issue to post the following:
1. Build date
2. Do you have Sport Auto Trans (option code 2TB) or regular Steptronic?
3. Do you have the same issue when the transmission is placed in "Sport" as when it is in "Drive"?
4. Does anyone else (wife, child) use the same key / profile? Or do you each have your own?

I suspect the issue may be the adaptive transmission learning your driving style. Or it may be an engine management issue - throttle position sensors (TPI's) have been problematic in several BMW models, causing the vehicles to "bog" under acceleration.

2017 540i MSport
