Wow, that's a lot of errors to get overnight, you sure you didn't feel any changes in the ride in the last few days? Is the battery well charged?

Thanks for the reply, I thought it sounded abit loud since I bought it a few weeks ago?

And you checked for errors with Lexia only once? If so, then we won't know exactly what the situation was right from the start ... maybe to try and do the BSI reset (some members would suggest doing this), just in case some errors are actually not errors, but glitches ... one description of the procedure can be found here (not sure if applicable to your C6):

BSI Reset / Battery Disconnect / Reconnect Procedure

... if it won't clear at least some of the errors, then your next step should be running tests with Lexia on each of the possible components, to see if it will give you any extra feedback ... after that, well, you go under the hood and beat the hell out of it ... ... whatever you do, good luck ...

How do you do the BSI Reset?

[Hell Razor5543]

This is how to do a BSi reset;

BSI Reset / Battery Disconnect / Reconnect Procedure

It looks complicated, and a common question is "Why?". Think of it as shutting down a PC (as opposed to putting it into standby). If you just pull the power any active files could become corrupted, whereas if you tell Windows to shut down it closes all active files, cleans itself up, and then shuts down cleanly. Well, even when you turn off the ignition and take the key out there are electronics still active (for example, the alarm system), so you need to shut these down as well.

Tip: do 2nd part, the reconnect part, in the morning after an overnight charge (if you do not have a load tester) to ensure your battery is 100%

I would say either the battery has had it; the fuse box has gone dolally; or one of the components that has a 5V control supply has gone belly up and is pulling the voltage down.

Check the battery voltage first...

If you disconnect the battery on a C6 REMEMBER TO OPEN ALL THE WINDOWS!! At least an inch or so. The windows drop electrically when you open the door, and if you close the door without this having happened- broken window...

Random multiple errors reported on the C6 forum are invariably caused by dead/dying battery, as Richard said. Don't forget the battery's in the boot.

It wouldn't be the first time that a fuse box has failed, although it is more Han likely a battery issue......

good advice about the Windows, a definite must.......If you are unsure where the battery is, then open the boot lid, there is an access panel on the near side, the battery is behind there, NO having said that, it's in a pig of a place, you may well have to remove the boot seal and pull away the side panel to get access.

I know Jodyone has mentioned http://www.c6owners.org" onclick="window.open(this.href);return false; but thought it might be a good idea to give you the address.

If there's anything else, just shout......... oh and welcome to C6 ownership
