Skoda Octavia control system for the exhaust

I just took delivery of this Car today. On the long journey home circa 160 Miles - about half way home the "Control system for the Exhaust" warning light i.e. the Engine Block symbol lit up. I drove it home the rest of the way at circa 70MPH expecting that it was generated by a carbon build up and the lively spin would clear same. The light was still on when I got home is it likely to clear itself or will I need to get it checked for a fault code. I have had similar problems with diferent models but they cleared themselves shortly after a hard drive.


Is there anything else I should do mysalf if it persists.

Thanks for the excellent advice available on the site,
