2012 Audi A6, instrument panel showing low tire pressure??

[z06bigbird]

2012 A6 does not use tire pressure monitors (TPMS) mounted on each wheel, like most other cars use. 2012 A6 uses speed sensors (in the braking system??) that measure speed of each wheel. If speed of one wheel varies, computer thinks that you need air in one tire.
Question. If I install my temporary tire, my computer will likely tell me that I have a (flat tire) problem. How do I get rid of that message.

1. Will the computer correct itself when I re-install the original wheel?
2. Will I need to pay the dealer to re-program the computer?
3. Same question, sort of. Will I need to pay the dealer each time that I get a flat tire?

Since the 2012 A6 has this new system, no one seems to know the answer to this question.

If you A6 MMI works like my A7's, then you can reset the tire pressure through the MMI system after you install the temporary tire and again when you go back to the original wheel. It's somewhere in the car setup menus.
