Car accelerates while in parki

Have a 2008 bmw 550i. I was wondering if anyone else has experienced this issue? The car was on, but the break was applied, and out of nowhere it started to idle exceeding 5000rpms. Weirder than that, the a/c started to blast cold air. Any thoughts?

My 530i was kind of doing that at one point when I first got it running. I would turn the car on and it would act like im slowly hitting the gas and it would rev up and idle at 5000-5500. The throttle body wasnt set right. Try messing with that and let me know if you can fix your problem... as for the cold air I dont really know.

I would take a close look at your voltage coming out of your alternator. I have had some weird things happen due to this problem, including idle speed hunting. Neal
