As jonzy said, you can unplug the maf, and if it runs better then the maf is gone.
Mine's running abit erratic at the moment, i took the maf off on sunday, and gave it a clean with contact cleaner, and reset the fault code, and its flying again today.
Im gonna disonnect the battery and reset the TB, and see if this helps.
Ask ninja about the vagcom, as im sure he's local to you.
