Yeah that's not normal, there should be a chorus of faint ticks from the injectors but certainly not one loud tick like what you have.
Could be a bad injector or something in the EGR system or even a mass air flow component clicking loudly like that.
It seams louder when you got the camera over to the side of the top plastic shield, I would remove that and try to narrow down where the clicking is coming from, holding a large screwdriver against things can sometimes amplify the sound when held against the offending component or there are inexpensive mechanics stethoscopes available at places like harbor freight which are very helpful at identifying noisy components, if you can identify what is making the noise you can drive without the plastic cover to a different dealer and point at the noisy component and say that is the thing that is making the noise.
Or of course you could just take it into a different dealer, you already know by now that the service department at your dealer is not where you want to go as they obviously are just trying to brush you off.
