Engine Ticking noise, is this normal?

[GGMan]

Hi

My Audi Q7 (2007) has some ticking noise coming from engine, is this normal?
Ticking definitely coming from the sides of the engine.
Starting to here it more when accelerating, even over music. (Might be hearing it more because I'm being paranoid about it ;)

Here a video, best to here it with headphones as you can here it louder when I move mic to sides of the engine.

I looked at a few videos on YouTube and cannot here this noise and read is some USA forums that this noise is normal?

 

 

Just some advice on this.

Thanks
