It's similar to the old carburetor cars where they'd get hot, and the fuel would boil in the carb while running, and you'd get all kinds of off idle bogs.

Anyone else notice this in the x1 35i platform? No noticeable different in sport mode vs regular.

Do a search on throttle lag. I think this has more to do with throttle adaptation that many complain about. There is a reset procedure you can try:

I use manual mode all the time and do not notice any lag whatsoever but maybe the adaptations do not apply in manual mode.
