MY14 D4, my issue is all worked fine one day, went out the next morning and nothing. Had to get roadside assistance to 'break' in, found wiring look along passenger side flooded, have been drying it out and have eventually got engine to start...
Having the same issue with my MY14 D4 (I don't have sunroofs here in Aus), water ingress from the A-pillar trim I suspect.
Can anyone confirm whether the same 3 green wire re-splice will work with a D4? I haven't been able to locate the wires...
