IMHO, If there were going to be mass failures in our T5's, The signs would have been appearing by now.......maybe they still will, only time will tell.
I was told that our DSG's are rated to 600nm or torque. Also that the T5 DSG is a wet clutch system, whereas the problematic passenger car DSG's are a dry clutch system, and are not rated to high torque values.

Here is an interesting article about the DSG.
