Hi everyone. I bought a new 330i this past saturday. Everything is fine, except for one thing. Every so often, I start hearing this soft whirring noise that sounds like it's coming from underneath the shifter (it's an automatic). The whirring gets faster as I accellerate, and slower when I decellerate. BMWs are so meticulously engineered that I'm pretty sure that sound isn't supposed to be there. Has anyone else experienced this? Thanks.
