Hey all, I have fixed my problem as earlier discribed.

I pulled appart the dash to find any air leak but nothing. So I decided to look under the bonnet and found a black hose sitting there not attached to anything. After some careful looking and playing about I found where it went.

In the intake manafold at te firewall end there is 3 attachments coming off it, the middle one there is a rubber boot where that black hose fits into. After pressing it back in my air vents work normally.

I have attached a pic, but with all the hoses it is not the bes.

Hope this helps
