Sure this isn't a coil on plug or the channel gizmo by the aircleaner cover.? (super easy fix)
See this page:

see the solution at the bottom (non coil pack)

Hi Tony,

I get 2 malf codes from vag-com...

16684 -  Random/Multiple Cylinder Misfire Detected
          P0300 - 35-10 -  - - Intermittent
16685 -  Cylinder 1: Misfire Detected
          P0301 - 35-10 -  - - Intermittent

I ohmed out the plug wires and put in new plugs when I did the belt 
about 4 months ago.  Doesn't seem to do it at idle,  does it cold and 
warm and almost exclusively at lower RPMs.  Seems to run good at WOT.  
There's about 130k on the car.

Tihol suggested unplugging the maf and see if it goes away,  an 
excellent suggestion that I'm going to try tomorrow when the wife gets 
home with it.

Best,

Bill
