Default Rough Idle -- VAGCOM results inside

The car isn't throwing any codes, I scanned block 003, 032 and I have no idea what these readings mean. Any ideas?

Whoops, I'm sitting in this guys car right now trying to figure it out and i forgot to post why I'm logging all of this.


Basically in when you let the car idle the rpms fluctuate from ~800rpms to ~1300rpms and bounce up and down like that.

He posted a thread before and somebody said it could be the MAF or TPS, so I scanned block 003 for the TPS measure and 032 because this thread said it shows important stuff. []

HALP!

Stupid question I suppose, but did you try adapting the throttle body?
