For Magneti Marelli clusters (e.g., New Beetle and Audi TT), you can try 2 different ways to dump the EEPROM. (replace "COM1" with the port that your cable is using)
For your Audi, I would try this one first:
.\kw1281Test.exe COM1 9600 17 DumpMarelliMem 14336 2048
Only if it doesn't work, you can also try this one:
.\kw1281Test.exe COM1 9600 17 DumpMarelliMem 3072 1024
If either one works, let me know and I'll add it to kw1281test. If neither one works, there's not much I can - unless some generous person wants to donate one in the name of science
