I've a 2.0 TDCI Ghia 2006, mk3, Ford Galaxy. When i press the cruise control on button it apear on the panel "cruise control stand by". Then, when i press either set+ or set- to activate, cruise control switches off ... This is new, and shouldn't happen ! I take the car to the ford garage, and they plug the car to the computer and couldn't find anything wrong ... they just unplug the battery wires and the problem seams to disaper ... but, after one hour of driving in the higway with the cruise control, the problem apears again.... Anyone has the same problem or knows a solution ?

Thanks in advance

Best regards
