Airbox flapper

Done plenty of searching and found the great guides on here related to this. Carried out the test today using VCDS and it is not operating.
However when engine is running the flap is open. Once car is off and vacuum dies off the flap closes. This appears to be working in the reverse of how it should.
Is it possible this has been changed by a previous owner to be forced open all the time using VCDS?
