Idle Rev movement...
Initially had this problem from about 2000 miles onwards on my car, I know a few other guys have experienced the rev counter bouncing up and down at idle...CHECK YOUR COOLANT!
Had a low coolant warning light the other day that immediately disappeared once I started driving, well it came back on about two days ago, but again disappeared right away. Thought something must be wrong so I checked coolant res to find it wayyyyy below the "min" level. Topped it up, and my rev bounces have stabilized at idle...give it a try if you've had similar issues!

I think it has to be a coincidence. I don't even run use my coolant tank since its used as my methanol tank and I randomly get the rev bounce. Usually happens when the car is cold and not warmed up. Someone previously posted saying when the O2 sensors were replaced it went away.

Just wanted to chime in again, my coolant tank was full so as expected makes no difference in idle bounce.

Similar to this idling issue...
I don't know if anyone else had has this issue, but my 2012 DCT has "stalled out" when rolling at idle twice in the past year of my ownership. I haven't been able to look at the rev limiter as it happens because its so sudden. Basically, I just remember a "shaking" of sorts that I can feel through the pedals and then next thing I know I'm in Neutral. Just happened last night and had to come on here searching for answers.

I have PPK and still think the throttle response is sometimes slow...but I have manual trans. again, not sure about DCT...I know there is something called a Sprint Booster that is a piggyback for throttle response but I havent heard of a single person using it, which makes me question if its any good...

Similar issues specially after a long drive and on a traffic jam.. Revs suddenly go up and car goes into N. dealer could not reproduce. I tough that the only crappy stealership was Autogermana in PR. But I see is happening elsewhere.
