How do you check the maf with vag-com? I have the cable but I have not been able to get to the graph or the reading window, thanks for your replies in advance.

Off the top of my head, I believe that you can go to advanced measuring blocks under "engine" and you can select a box marked maf. From there there's an option to datalog graph it.

Edit:

Air system part I: MAF
  • Go into Engine measuring block 003
  • Start Logging data
  • In a high gear (4th/5th), give full throttle from 2500 rpm up to 3500rpm.
  • Find and Open the Log file in Windows Explorer
  • Graph MAF actual -vs- rpm in Excel
  • The MAF is OK if the actual value is at least 850-900 mg/h at 3000 rpm.
