Stopped by the stealership today to check on the rattle/knock noise coming from the engine bay, which is very slightly audible from the cab; however, the tech that looked at it claims that he heard 'nothing'. Popped the hood and he says it sounds completely normal. He called another tech and asked what he heard and the other tech said it sounded like a '6.2'. They both claim the sound is normal.
Out of the 15,666.9 miles and 1 year 4 months and 11 days I have had this truck, I have never heard a noise like this one EVER. I have tried to take a video of the noise, but no luck as it is very slight and is overwhelmed by the ticking noise (had this sound since new), which the 2 techs claim are the injectors. The sound is intermittent, but I think it is somehow linked to the A/C because I only hear it when the A/C has been running for quite some time and it will stop after the A/C has been turned off for a while.
I remember there was a way to check for codes via the factory navigation. Can anybody instruct me how to do that?
Also, does anyone else have this noise? I know I cannot describe it well, but if you have any slight knock/rattle sound coming from the engine bay which is not the ticking/chattering noise please let me know, so I can see if it is 'normal' or not.

Nice. Does this ticking noise sound like a rod knocking?
Yes it does. Is that normal?

This noise is driving me ******* insane. I hear it now everywhere I go, even when I am not near the truck.
