I’ve done a search but found nothing on this. I’ve got a startline T6 that came with factory electrics options done, aircon, parking sensors, powerful mirrors and I’ve acquired a highline light switch that has auto function. I’ve swapped it out and the switch works fine but in auto function it puts the headlights on all the time. Do I need to do coding in vcds to sort 
this? There must be a sensor somewhere as the dash lights dim in different light conditions. There is also a rear view mirror with a sensor and a power button on it. I’ve no idea if this is factory or not.
