So today I get the check coolant level light... It's been a while since I have seen that one...rather annoying...

How do I check and reset service codes on this 2005 c6 MN6?

There is some kind of procedure and I forgot which buttons I have to hold down and for how long....

The procedure has changed for the C6. You need to use a scanner.

The procedure you are remembering was from the C5. You could hold down the options button and press the fuel button four times to bring up a list of your DTC's.

That feature was disabled in the C6. The only way to read the codes is with a code reader. Find yourself a CAN BUS capable OBDII reader and you will be all set. No other user accessible way to get at the codes.

You cannot get the codes on the DIC like you could on the C5. You must get an OBDII reader, preferably one that is CAN enabled.

Wal-Mart sometimes has an inexpensive one.

Check Amazon and eBay. You can pick up a very nice scanner for $50-$100 depending on features.

Do you guys have an Advanced Auto Parts near you? They will check and reset your codes for free. No I dont work for them. I mentioned them on another thread as well 'cause theyre the closest auto parts store to me.

I changed the spark plugs and wires after getting the code P0207. I currently still have the CEL on and a code reader. Do I need to clear the code in order to know if I fixed the problem or should the CEL light go out on it’s own?

Welcome to the forum. I know you are a new member, but why would you piggyback a 10 year old thread to ask your question?
Simply start a new thread, which will be relevant.
To answer your question, the code is for injector 7 control circuit, and you will need a code reader to clear the CEL
