weird experience with my n54. help?

so I was heading out to grab some take out for dinner. stopped at a light to make a left turn and waited for traffic to pass. when it was clear, i took the turn only to notice that my engine went up to 5000-6000 rpms but i was only going at 20mph? i let the rpms drop a little before stepping on the gas again but realized it just did the same thing. it was a good thing the road was clear so i braked to a complete stop and when i stepped on the gas again, everything seemed normal. anyone experienced this before? anyone know what caused this? hope someone can help a newbie out here. i don't want my car exploding on me lol.

Take advantage of this once in a lifetime opportunity! You're car is one of only 576 in the world that are capable of time traveling. The car revs to those RPMs for 7.98346 seconds before burning out and sending you into time travel mode. Good luck with your new found power!

Do you have paddle shifts on your steering wheel,cuz sometimes I'll click it into M1 even when it's on D and the rpm will go to 4000-5000 and then shift into D again on it's own.

Yes! Just make sure to set the time to the year you would like to travel too -- otherwise you may be in for a bit of a surprise!

ah yes that might've been the problem. i'll see if it happens again in the future and whether it switched to ds. thank you so much for your help!

Did it feel as if you were accelerating at high rpm in low gear or as if you were free revving in neutral? My car did that once (acted like free revving but was in Drive) shortly after the dealer had updated the ecu, parked and restarted the car and all was well. Its never done it again after 20k+ miles, not sure what caused it but I assume some strange glitch as the car was re adapting to the new software possibly.

yes it felt exactly like that. my girlfriend back home drives a 520i and she experiences the same thing too and she doesnt have pedal shifters so i guess the previous theory was out the window. you went back to the dealer to update the ecu and it was fine you say? maybe i should do the same too.

No, it actually happened shortly after the dealer programmed the new software on the car. I just assumed it was something odd with the car adapting, my trans was acting a little strange at low speed/ light throttle shifting for a couple days before it smoothed out and its been fine ever since, 2+ years now I think.
