Idle Speed via VCDS

[Duster90]

I need help adjusting my idle speed with VCDS. The three main codes for security access seem to not work. 27971, 79153, 12233. Every time I try it says seed not sent. Maybe I'm doing something wrong.
My idle is sitting around 740 RPM. I'm looking to bump it up around 50 to 100.

Do not believe you can set idle speed on your particular car with Vcds.
