F10 N55 start/stop feature issue

Heathryan · 01-10-2013, 06:21 AM

Has anyone else had their start/stop feature reversed so that it is always off and you need to push the button to enable? I went in to have this done last week and my car came back different. I felt like it was detuned. It has noticeably less torque off the line in any mode (comfort or sports).

Anyone else experience this? Any suggestions on how to resolve?

I didn't realize this was possible. Is this the dealer which performed this operation?

(And if it's dealer, can you just go back to them and have them check it out?).

May have just reset adaptations and it needs to relearn the way you drive. Reprogramming is not going to detune your car.

To reverse the MSA (Stop/start) the dealer must program the vehicle. This is done by request only

Thanks for the feedback Juiced, what do you mean by relearn the adaptations. What I am experiencing is something that seems to be consistent with the issues other 1 series N55 owners have discussed in some other threads I just recently found.

My car came back with a huge difference in torque after being programmed to reverse the start/stop feature. I only have 1200 miles on it so my Comparison is limited but it is that noticeable, especially in certain areas around home where before I could easily put myself back in the seat taking off or coming out of a turn and now all I get is a pause while the car down shifts and then revs up much higher than before to achieve less of a takeoff. Make sense?

Thanks for your input...
