Help - Funny noises and lurching
New to the E63 world. I've found that sometimes under moderate acceleration with the engine on for about five minutes, the car chokes so hard that I'm thrown forward. Usually happens a couple times and then it goes away after driving for a bit.
Secondly, under fairly heavy acceleration I sometimes hear this whining noise almost as if there were a supercharger. Is this the transmission or something wrong with the engine perhaps?

Your input is much appreciated!
Thanks,
TTR
