I was traying to change the value for service interval from 30kkm to 20kkm, but I wasn't able to do this. I was able only to restet service and change the cycle count. Do anybode else tryied this?

I have same problem with Fiat Punto 1,9JTD made in 2003 (new model MY'03)...

Works fine with Fiat Stilo 1,9JTD, but with others... no luck...
