Strange revving while stopped at Red light

Not a 2000rpm surge

 

I have reported the same erratic idle to my dealer twice and they are unable to reproduce the problem. I finally recorded it and will show them the next time I'm the dealer to get my entune head unit replaced for randomly shutting down. I will report back with the outcome.

 

I would tell them I'm concerned and that this is a safety issue, as it could lead to "sudden unintended acceleration" for which they never could find the fault.
Let us know what they say.

Hope that helps
Cheers!

 

Mine does the same thing. It seems odd but is not enough of a rev that I would consider it an issue. It's maybe a 500 rpm increase. I figured it had to do with the AC. I wil bring it up at my 5k service so they can tell me nothing is wrong.
