Hi guys,
Hoping some of you friendly folk can help.
I've got bi xenon headlights on the Vito, however drivers side xenon bulb is not lighting up, all other lights in the unit are. So we try the obvious, change the bulb, no change, then I try the bulb on the other side which works, no bulb issue, so I replace the ballast, and nope, still not working, so out comes the headlight, and I plug it in to the other, and it still doesn't work. In a money spending exercise I purchased a diagnostics reader, now is this telling what I might think is obvious? I need a new unit? Appreciate all your help and advice
