My car's been shifting a bit rough lately, so I emailed my SA re: that and another issue. I told him how I had tried this trick of holding down the accelerator. This was his reply:
"As far as the transmission is concerned I would have to get the car here drive it and scan it for codes.... The method you tried will not correct anything... "
This guy's pretty knowledgeable, so who knows? It sounds like he's heard of this, though.

This is surely very odd. BMW recomments you drive the engine belwo 4000 rpm and 100 mph for the first 1200 miles for breaking in. Surely the driving characteristics are not normall during tne first 1000 miles for them to be used to "lock" in the driving style.
Would my other learned friends on this forum verify or confirm this. Can it really be reset? Why is it not in the manual. Surely this needs to be done often if the ownership or the car changes over time.

Just to confirm, I have an 04 530D auto Touring (i.e. it has a normal key), is this the correct procedure:
- turn ignition key so that ignition is on (one before the starter position), no feet on brake.
- floor throttle for 25 to 30 seconds all the way past kickdown
- take foot off throttle
- turn ignition off
Once this is done I can then just start it and enjoy?
Thanks

From what's been described here, I would have thought this is a throttle position reset rather than gearbox?
It would make sense that you're telling the computer where zero and full throttle PEDAL positions are by doing this. From that info the computer then knows how much to open the throttle. Maybe that's why dealers don't think it will reset the auto box - because it doesn't, however it does reset the throttle/pedal position parameters.
Makes sense to me but I could be talking rubbish! Anyone else care to comment?

Un-frickin-believable....
I've got 50K miles on my 05 545i. I've had a nagging problem of throttle hesitation from a stop when in D. I drive in DS for two reasons:1) no hesitation, and 2) I prefer the driving experience and shift points.
Despite whining to the dealer and various SW updates the hesitation has been present since the beginning - until 24 hours ago when I performed the reset. Driving in D is now a pleasure, but it still doesn't compare to DS!
Awesome find....

After putting up with rough shifting and expecting to R&R the transmission I used this technique on my 2001 e38 740i. I had read about it in a BMW Magazine ny daughter picked up in Europe.
Since that car didn't have a "start" button I simply turned the ignition key to the start position twice [without actually starting the car] and floored the go pedal. No noises ... but it worked! When I told my independent BMW mechanic about it he was going to try it on other customer cars before they resorted to more expensive transmission work.
Shifting problems immediately disappeared and stayed away for more than 1K miles ... the car seemed more responsive overall. I still decided to trade it on the '07 530xi that brought me to this forum
.
Never look back!

will this work with a SMG tranny???????????It seems to make shifting smoother on my M3 and makes it easier to use sport mode without the bucking bronco.
