Polarity correct? Or maybe like I had, activated the wrong option in service mode...Hi guys, i activated the fog lights in service mode, turned them on, but apparently I don’t get 12V on any of the wires. I tried connecting one fog light with no succes. Any ideas ? It’s an European 2022 model…
Unfortunately my fog lights didn’t arrive yet, so I have an off-road 12v led light handy and I thought I would try only one. And it didn’t work. After that I tried measuring the voltage. Do you think it may need to have a load on both sides?One other thing, do you have lights connected or are you just using a voltmeter to check for voltage?
If the latter then it may be possible that the BCU needs to see a load before it will output a voltage or alternatively if not OEM lights then it may be they are drawing too much current and the BCU is not allowing them to be switched on.
It’s a 12v - 18w light, shouldn’t be to much at all.I think the wiring is just parallel so shouldn't need both connected but maybe the light you have is too high a current draw. Not really sure though, I am just trying to think of reasons you have problems.
I do not have an AT yet. But I think that menu you show in the picture, is for the DRL, or Halo Leds.Yes, I turned them on from FN and voltage is zero.
