I've had my 07 M5 6spd for about a month now. It's got around 11000 miles. Since I got it I've noticed that just above idle I get very poor throttle response. It feels like a bog. Of course as the rpms rise all hell breaks lose. The only way I can explain it is it's kind of like a bog off the line. This happens under load and in neutral simply reving. Happens hot and cold. I use only Shell gas and have not added any cleaners.
Any thoughts?
I have 6 weeks left on warranty.
