Does this idle sound normal?

[VIPNiSS]

I am not sure if I am being paranoid or what but I just bought this 2008 CTT. Can you guys listen and tell me if this sounds normal? PARTICULARY the passenger side of the engine.

I can't say if that sounds normal for a CTT, but I definitely hear a difference on the right (passenger) side.  Others that know far more than me will undoubtedly chime in, but, depending on what they say, I would take it for a scope to get it checked for the dreaded cylinder scoring on that bank.  Hope for your sake that it's nothing.

Right side sounds normal compared to my non-DFI '06CTTS but the left has the air flow sound. Maybe that is the Breather on top of the head although I have one too, doesn't look like the design of that has changed. I'll listen to mine today and see if I can hear the air flowing. Doesn't sound like anything bad, just an airflow sound through a pipe or hose, not an airflow leak. Does it run fine? Any codes?  If yes to both then it is most likely fine. Congrats on the newer Pig.

It's hard to tell from your video due to all the mechanical noise of the fuel injection system, best to find another cayenne to compare it to.

no codes or anything and runs fine.. just paranoid.. but its almost like a small knocking sound or valve clatter.

This ticking on the right definitely sounds like injectors firing and I think the DFI injectors are a little louder, may have to do with their higher operating pressures.
