Gang,
I've noticed in my 2011 550i that it has a vibration under light throttle. It seems to be throttle based, but it's only under light load like 1700 to 2300 rpm. Is this unique to me? If not, is there something specific I need to ask the dealer about?

Thanks,
Scott

Did you guys find a solution?

Is this when going straight, or around corners?

I find I get this same problem ONLY when I try and accelerate around corners (e.g. on-ramp/off-ramp near motorways when you want to put your foot down!)...

I never got an answer to my thread as to why this happens, but I suspect still that it was due to the electronics controlling the vehicle forces and so limiting speed while the tyres/wheels were at risk of losing traction.... as soon as I hit the straight the sound disappears and you feel a surge of acceleration. The noise in my view is the combination of engine trying to accelerate (and revs go up), but the car is limiting speed...

(I love showing this to passengers, put your car in cruise control, go around a corner where you know you would normally brake to slow down, and the cruise control takes control and slows you to a safe speed and speeds up once you are on the straight... clever tech!)
