A8 ECM coding

[David Giannandrea]

 I had an incident with the serpentine belt. It disintegrated. Then I
decided to drive the car anyway till I got it home (without AC,
brake/steering assist, alternator). I almost made it.

Engine quit running a short time after the 'Battery' icon displayed itself.
Now, after charging the battery, I still can't get it to run. Used starting
fluid, ran ok for a minute, died.

The ECM threw the following codes: 
	18010 - Power Supply too low (as expected)
	18020 - ECM incorrectly coded

Manual says to start car without any throttle movement, wait for adaptation.
I will be doing that today.

Any other suggestion about how to 'code' the ECM ??
