Audi Reveals Software Fix for 3.0-liter TDIs

"and would like to save my current ECU settings in the event that my worst fears are realized. "
That's easily done.
1-Buy a current ECU from a junkyard, or someone who is selling one privately after replacing it with a "tuned" chip.
or,
2-Buy a "tuner" kit that piggybacks and allows you to copy and save code loads. Surely there's at least one around, although it won't be cheap.
3-Hire a guy with a code reader/writer to read to store the load in your ECU now. This is done all the time with all kinds of computer chips, the trick is to get a guy who can work with your chip.
Of course if you should happen to restore the original software, and somehow that comes to light (say, by a dealer's ECU check or an improved state emissions test) you'd be red-handed guilty of a federal emissions tampering violation, which could cost as much as replacing the car.
The choices are all there, roll some dice, pick one, any one.

I would go for 1. Replace the ECU with the bought one just before the ECU update and then switch back as soon as back home. Then every time you go to a dealer or for emission test you can just switch them back and forth. It won't be that often especially after warranty expires.

flash your own ECU and create your own backup tunes... Flashing and Chipping

Guys, make sure you know technically what is required in ECU swaps. The recent ideas in the thread seem to assume you can basically just freely swap ECUs with what ever coding. It's not just plug and play like it was pre-circa 2001 when the ECU started getting tied to the immobilizer function.

Not suggesting or commenting on advisability of doing it, but rather the practicalities and challenges involved to know about.
