Lightbulb Help with CEL P1098 Intake Manifold Sensor + P2187 Too Lean Idle

My 2005.5 B7 2.0T has a check engine Light with two codes:

P1098 - 004248
Intake Manifold Tuning Valve Position Sensor (G336)

P2187 - 008583
Bank1 System Too Lean at Idle

The engine has needed a quart of oil added recently.
Replaced blower motor in 2011
I have noticed ever so slight sluggish performance lately.

Any suggestions on what to do first?

When my Jetta got that Lean Bank on Idle, it turned out to be a bad mass air flow sensor, which is just after the engine air cleaner. Don't know if it's the same code as my car, its been a long time since it happened. Never had this happen on the A4.
