2013 M56xS. 103000. Beautiful vehicle inside and out. I have a concern. Seems that when the car is in drive with my foot lightly on the brake pedal and I start creeping forward, it's not a smooth creep. In other words that low speed movement I can feel the engine firing the cylinders almost as if the car had a performance cam in it. Cleaned both throttle plates.My idle is dead on around 500rpms. Anyone know what the idle spec should be? If it's low what can do to bring it up?

Have you had a chance to review the Factory Service Manuals found on this site? I believe that information would be in there. I think mine is around 600.

Actually I haven't but that's a great point. I'll take a look. Have you noticed the same condition I was describing earlier with low speed creep?

Mine is 600, too. Also, you may want to do the idle relearn after cleaning the throttle bodies.

I have not. All my car has is a touchy throttle, but that's due to my UpRev tune .
