In New Zealand, the equivalent to a MOT is a Warrant of Fitness. All lights are expected to work if fitted. I have just had something break one of mine and I am currently sourcing a replacement for it. In order to remove the light symbol on the dash and the warning message on the coloured screen, can a tech2 unit be used to disable the fog lights to remove these warnings until such time as the replacement has been received, in order to get my warrant? If yes, is it just a simple thing to follow instructions or does anyone have a guide to the required setting(s) please? I have a 2006 Vectra Estate, Design trim.
