I just bought my ScanGauge, so I'm not as up to speed as some others. But, if you take a look at this link, it says that you can monitor four different catalyst temps: http://www.scangauge.com/support/xgauges-for-cansf-vehicles/
I guess the only real way to tell would be to play with a ScanGauge and compare these "catalyst temperatures" with the VCDS readings of the EGT sensors. These catalyst temps may (or may not) directly correspond to TDI EGT sensors. If anyone has a ScanGauge, VCDS, and a CR TDI, this would be interesting to know. I am not going to buy a ScanGauge just to find out if it works.
