    Hi i've recently retrofitted the ecode for my 07 a3. The headlights work but i don't know how to make the DRL work. Since i got the car with halogen lights my original switch does not have the DRL. However i bought the TT chrome headlight switch and has the DRL but no plugs for it.

    Anyone know how i can make this work? probably a part # for the harness that goes in there?
    The 2 small wires aren't plugged in, only the headlight wires are in place. since the small wire plugs are already in use.

    this was the diy i followed

    What is the module version in vcds module 09 for a start?

    You need to wire the drl's in anyway aswell as coding if possible or they wont work properly.

    Ideally the central electrics board needs to be a 23byte version F upwards to be able to code the headlights properly.

    You will need to also make up the wiring for the headlight switch missing plugs with connectors from audi & repair wires, also you'll need elsawin to know where to wire everything, have you got vcds & elsawin?

    What is the headlight switch part number out of interest, assume its the seperate dial drl switch, does it have the ch/lh button aswell, which would be the E versiion headlight switch?

    for the DRL wires, something else is already in use in the plug that hooks up into the ECM. So should i try swapping the wires out? or tap it? I don't have a elsawin but i do have a vagcom i can borrow it from a friend.

    As for a switch this is what i'm currently using
    http://oemplus.com/index.php?main_page=product_info&cPath=60_61_103&products_id=405

    Originally my car came with no tech pakg, or anything just halogen lights.

    The bixenons work fine with now with the coding i had to change from the DIY

    this retrofitting DRL seems alot of work!!! :(

    thank you for your help!

    Get hold of elsawin just to verify/check what the existing wires are for mate.
