    Front fog lights won't light up

    Hi

    My Astra Mk5 Estate had wiring in place for front fog lights.
    I therefore decided to install front fog lights

    I have changed the light-switch, mounted and connected the fog lights, checked that I have the needed fuse (in front fusebox, 15A in slot 13). I have full REC.

    I have used OPCOM to set front fog lights to "Present" two places; Body -> IPC ECU and som other place.

    If anyone knows the exact places to program the car to recognize front fog lights, please let me know.

    I can test the fog dash lamp with OPCOM and it works fine. I also succeeded in setting comfort closing, so the OPCOM device works fine.

    I'm getting desperate being so close to get it working, but just can't get over the last barriere...

    Further info:

    I can use OPCOM to test the actual fog lights, they light up fine with the test-tool!

    I have reset fault codes, but three keeps popping up:
    - U2140-71 Invalid Data from UEC (Underhood Electrical Centre)
    - B1020-00 No Communication with Rain Sensor
    - U2140-71 <Unknown DTC>

    The rainsensor makes sense, as it hasn't worked in the short time I have owned the car. This is probably inside warranty, so I'll let Opel deal with that.
    The other two are a bit more interresting...

    Anyone fancy give a helping hand?

    Maybe you haven't got the wiring from the headlight switch to the instrument panel? I posted what wire colour this is in the long fog light thread over the weekend I believe

    I'll check it tonight, if I don't have it, is it possible to wire it in?

    Where in the instrument panel are the wires from the headlight switch terminated?

    I would think that it should be there already, when I have fuses in place + there was already wiring in place from instrument panel -> left/right fog light.

    OK, just checked the headlight switch, out of the 12 pins on the switch, I have 10 wires going into the instrument panel, and one of them is grey/blue.

    What to do next

    Is that the one where you have to unscrew 3 torx and remove the fuse board?

    Gonna check that later tonight (kids, wife and regular work all have their share of our time).
