197 Emission Warning Message

[Elsegood]

I've had a decat pipe fitted to my 197, and I now have a warning message on the dash saying 'Check Emissions'. I thought maybe this would disappear after the ECU reset or got used to the exhaust kicking out more fumes.

Is there an easy way to reset or remove this message?

I know it's self inflicted, however it's getting very annoying now as it's been a few weeks since the pipe was fitted.

Any ideas guys...
