Knocking noise at low speed possibly around dashboard area?

[renton]

Hi all,

 

Recently picked up a 2.0 petrol sportline and for the best part I'm extremely happy with it.

 

However I've noticed a knocking noise coming from the front of the dashboard area at low speed. I thought it may have been dry seals on the sunroof but Ive coated them and its made no difference.

 

The car drives find and doesn't clunk coming on and off the drive. Its as though the car body is flexing and causing a knock somewhere? 

 

Anyone had similar?

I get knocking coming from around or behind the AC vents in the dash. No idea what it is and yes it’s annoying. Seems to do it more so just after the cars started. I just turn the radio up!!
