Loud Blowing Sound in dash

Afternoon Guys

My Nav has developed a loud blowing sound coming from the dash, sounds like its behind the radio on the passangers side, and the noies builds with engine revs like the sucking of the snorkel, any ideas?

Cheers

if you have the 3 litre it could be the EGR pipe has cracked. its right in front of the firewall and sounds like its just behind the dash.
