Chausson on Ford chassis 2015. Have a service message up on screen , have tried all the usual fixes ie push brake & accelerator pedal together etc ( followed to the letter) and warning goes away (great) !! But when I go to start up vehicle the Service warning comes back on again ? Service not due it's only done less than 500 miles, ha! As I say the usual fixes ain't working so looking for something a bit deeper I feel , anyone had a similar problem ?
