Start with a VAG-specific scan tool.

Chances are it will need a MAF sensor, but I would still want to see what a real scan tool says.

A VAG specific scan tool would give you code 16786

And possibly other DTCs and who-knows-what-else in some of the other modules.

If you need it scanned (and want to drive to Galion, Ohio) let me know. I have VCDS and can do it for you free.
