    I've just ordered my 4300k HID kit and was wondering if I will need to modify my wiring to keep the dipped beams on when I select main beam or will the kit plug in and do this for me?

    The kit will just replace your dipped bulb assy that's it.

    You will need to do the mod yourself unless you had fogs in your headlights before, in that case it will already done

    That's cool. Any idea how I do the mod or am I going to have to get geeky and look at my wiring diagrams. Have to be honest I'm feeling a bit lazy these days with modifying.

    If your car currently has H4 bulbs, it will shut off.

    If it currently has H7, it will stay on.

    My car is pre face lift but I have added facelift lamps so it doesn't keep the dipped on when going to main beam

    I remember seeing the write-up on here somewhere. You just needed to bridge two adjacent pins on the connector to keep the dipped on I think.

    Can't imagine it would be good for HID's being switched off and on so quickly, eg: when you were flashing someone.

    Indeed mate, which is exactly why I want to do this mod. I don't fancy going from main to dipped and finding it all goes dark. lol

    H7's dont come in "hi-lo"

    All facelift light units use H7 bulbs.
    Prefacelift had two different headlight units, one was made by Valeo, and had a single H4 bulb, one was made by Bosch, and had a pair of H7 for dip/main and also a H1 foglight bulb all integrated into the one unit.

    I've just had a look thru the wiring diagrams to try and see what Audi did to hold the bulbs on, unfortunately the diagram only shows the Fog-Light equipped cars, so i cant compare the two and see whats missing, and theres no obvious interconnect either :/

    ok i'm guessing here, as the diagram doesnt actually show it, but if you look at your headlight switch, can you tell me if theres yellow/red wire on pin 8 or 10

    I'm thinking looking at this picture, that to hold the dip beam on you want it connected to 8, and to shut it off you want it connected to 10.

    These diagrams show nothing connected to pin 10, which would make sense given they're for facelift/foglight cars. Looking at the switch outputs, moving it to pin 10 would give the effect you get on H4 cars.

    whoops didnt read the facelift upgrade bit surely a multimeter would point to the right conections to bridge , would it need a relay in too ?

    Doesnt look like anything needs bridged, just move the dip beam connection from pin 10 to pin 8 on the headlight switch!
