Help!! ....Weird ALIEN noises coming from outside my house

[Helena]

Well apparently the sound is is coming out of my 2013 A3



Howdy, Audi Folks

I'm looking for help

Someone came to view my Audi A3 to buy today, but the engine sound put them off.

I'll take it Monday to see if I can get it diagnosed.

But just wondering if anybody here would have any idea what this clicking noise is when the engine is revved?

Or is it normal?

I've attached a video of the engine running

Thank you

Helena
