Clicking noise between 1500 and 2500 rpm

Hi,

I have recently purchased a Golf MK7 1.0 tsi bluemotion 2015. A few days ago I noticed a slight clicking noise when revving between 1500 and 2500 rpm. The noise seems to disappear after 2500 rpm but it might be just that it gets suppressed by the engine noise.

It's not very loud so it's difficult to record, so not sure if you guys can hear it:

The noise is there when the car is stationary and doesn't matter which gear it's in.

Any ideas?

I was like wait a minute, that doesn’t sound like a GTI, then I looked over at your profile and saw 1.0 Tsi, I was like oh that’s why it sounds like a v6...lol. Anyway, from the video it sounds more like a rattle, maybe a heat shield?
