Chain noise while coasting.
Hey guys , ive got a 2011 hemi. Basically what happens is if there is no strain on the motor and I have my windows down I can hear a ticking sound very similar to a bicycle coasting without pedaling As soon as I touch the gas it dissapears. Also no tick at idle, And Putting the transmission in the TRS mode and driving in 5th gear, no sound at coast down.
Selecting Tow/Haul mode, no sound at coast down.
Putting the transmission into neutral, the sound disappears.
In normal driving mode the sound disappears at around 1200 RPM regardless of road speed.
The common factor with all four is the MDS. (MDS is off in neutral, Tow/Haul mode, TRS mode, and at or just above idle. I specifically watched the ECO indicator and sure enough when the ECO indicator goes off on coast down, the noise disappears.
some of people say its the timing chain tensioner or the timing belt chain itself and some say its the camshaft, or MDS lifters.
here's a video the the problem exact same problem :
please am hopeless dealerships cant figure it out everytime they tell me somethin.

I know you stated the dealership can't figure out your concern, but were you able to do a ride along with your dealership to replicate the sound for them? Sometimes that can be really helpful!

I noticed my 11 ram crewcab is also making the same noise. Have a appointment made for next Tues at dodge dealer but I'm skeptical that they will be able diagnose the problem as they have never heard make that noise they said. And they probably will not listen to my suggestions I'm sure. I read the big thread from the link above and it does sound like a rattling timing chain or in that area. Hopefully the dealer can diagnose it. I'll post a link of video shortly.
