My car did that for a while but now it is fine. My guess was it sounded like intermitant re ignition of exhaust gases. Muffeled explosions causing the jerking.

In for a resolution.

I posted in the rough idle/motor shaking thread but feel this is a better place for my info since me and the OP seem to have the same issue. Mine has the same noise/feel at idle. Its a metallic clunk/crunch from the engine bay that you can feel through out the car. I've also noticed that when it happens there is a drop in rpms from ~650 down to ~570. It almost feels as though its an incomplete combustion, or miss-timed ignition on one cylinder. Problem occurs whether the engine is a cold or hot, although problem becomes more pronounced and frequent when the engine is heat soaked, i.e. after driving for an hour or more. No CEL and no codes pending. Problem also comes back after pulling the #2 fuse. Interested to see what you find out Bernd.

Mine does this too.

Mine's been doing it since day 1 as well. Hasn't gotten any worse, hasn't gotten any better. So whatever it is... Must not be too bad. Just an annoying sound and feel.

Someone in Massachusetts willing to help (engine noise)?

I came across this info from www.techauthority.com

2011LCOM1PDF
2011 Dodge Challenger Owner's Manual 1st Edition PDF ( English )
Manual Transmission

As follows,

Due to the high performance nature of your drivetrain, you may hear your transmission. This can be most noticeable when the vehicle is idling in NEUTRAL with the clutch engaged ( clutch pedal released ), but it may also be heard when driving at low engine RPM. Also, this may may be more noticeable when the transmission is warm. This is a normal condition and is not an indication of a problem with your clutch or transmission.

This pretty much sums up what I'm hearing.

The noise we are talking about is definitily not coming from the transmission. It is coming from the engine area. But tomorrow we'll have an appointment with our customer ( by the way Automatic transmission) to make some tests. The results we`ll forward to Dodge.
The noise you are hearing, you can make a simple short test. Press the clutch pedal totally. If the noise is still hearable it is not coming from the transmission.

hey together, we found the solution of this noise. It was coming from the front crank shaft pulley, the rubber damper in the pulley was lose and this made the noise in idle. New pulley is installed, no more noise.
