For anyone having issues with VAG talking to any one or more modules in the car.. the fix is very very easy.. this is for Windows XP other OS it may vary..

1)Plug your VAG cable to the correct USB port
2)Right Click on My computer and select properties
3)Click on Hardware Tab and then click on Device Manager
4)Open up the Ports (COM & LPT) and then right click on USB Serial Port (COM X) and select properties
5) Select Port Settings TAB Click on Advanced Button
6)Change Latency Timer (msec) from 16 to 12
7) Click Apply & OK on all windows and close them.
