I should have put this in my reply although it may not do you any good
now that it is at the dealer. Code explanations are on many sites to
determine what they mean. I use an OBDII program on my laptop since
you can't open the C6 without it, has saved me and my family plenty.

How to Pull Codes:
1. Turn your key to the "ON" position, but do not start the engine.
2. Clear any present messages by pressing the RESET button.
3. Hold the OPTIONS button down, and press the FUEL button 4 times.
(This will get you into the "codes" section of the DIC.
4. The computer will automatically display all the codes your car has
created. It will cycle through each code every 3 seconds. (Have a pen
and paper handy to write down the codes)

Note: Any code that ends in an "H" is a history code (something that
has occurred in the past, but is not reporting as an error currently.)

5. Once the computer has finished going through all of its codes,
press RESET to enter Manual Configuration mode. It should start with a
module and show "NO CODES" or "# Codes."
6. To optionally reset codes once in manual mode, press and hold RESET
until is displays "NO CODES."
7. Press OPTIONS to go into the next module (ie, from PCM, or
Powertrain Control Module, to TCS, or Traction Control System.)
8. Repeat Step 6 until you have reset all the codes in all the
computer modules.

Note: Only reset the codes if you want to- it is not necessary to
reset them every time you pull the codes.

9. When finished, simply take your key out of the ignition.
