2010 S6 - about to purchase, engine video

Hello Audi Forums,

I am new here, about to purchase a 2010 S6 and I would love it if someone would watch this video and give me feedback? It’s the engine bay, with engine running. I hear a ticking noise, was curious if this is normal.

Car drives amazing, it’s lowered, has Milltek exhaust, BBS wheels and new Michelin Super Sports, handles almost like my M3 (up for sale) and pulls like a monster!

Here’s the video:

Thanks for any feedback!
