As above its driving me crazy. i had a set of clocks supplied via ebay to find they looked new packaging etc, but someone had programmed them before. Now mr vauxhall say until i buy new set i cant use my fog lights,rear wiper,esp and i have no fan cutting in on long jorneys? I have the original clocks still as only the outer covers and afew snapped screws. (Again i was told it was a sealed unit by vx!) So my question is if i dissconnect my battery and put old cluster back in will the car start still? Or has the vx garage now programmed certain bits to the new clocks (like keys) that it would be now another trip to dealers to get old unit to work. i need someone to help with tech 2 experience ideally im thinking. Any help appreciated.
