Cruise control stopped working. 2009 model

My cruise control has suddenly stopped working. The symbol in the instrument dial lights up but the switches on the steering wheel don't seem to work. My dealer suggests replacing the switches. Is this a DIY job bearing in mind there is an air bag fitted. Any help appreciated.

Start with a diagnostic scan to see if the switch shows open circuit along with the function of the brake and clutch switches.
