I HAD THIS ON MY 05 STI IT WAS A VACUUM HOSE OF THE DV

 

All indications if you do a search point towards the DV

 

Right, had the inter cooler off checked all the vacuum hoses for leaks inspected the dump valve everything appears to be good...

Went to halfords got some carb cleaner had a spray around the inlet manifold
To see if there where any leaks but nothing

Starting to think sensor now but which one?
