    Coming home / leaving home retro fit

    Hi,
    ive been searching this for a while now and have found mixed tutorials and methods but am not
    sure which will work for my car.
    I have the a4 b7 2005 s line model with standard headlights no auto lights and no auto dimming mirror.
    this fit is on an a3, will it work on mine? This is exactly what i want.
    cominghomelights - Audi Retrofit

    Ive also found others but im not the best at electronics and not sure about lowline / highline models?
    http://bigskyeuro.com/images/gallery...H_retrofit.pdf

    Any ideas if this would be possible? Or anyone know someone that can do this for me?

    Thanks!!!!!

    To check if you have high or lowline take the headlight swith out and unplug it, if your headlights come on its highline and you need a single repair wire and some coding this is what I have, as for lowline that's involves a bit more wiring. I have a thread on here somewhere about it.

    For the system to work properly it needs the auto lights sensor on the windscreen to be installed and a high line module. If you have auto lights installed then its simply a case of installing a new wire and the switch for the ch/lh lights.

    However if you don't have a auto lights sensor installed you can still have the ch/lh lights working.the only thing with this is that they will work during the day as there is no way for the car to tell if its dark or not.

    I am part way through installing the auto lights install myself and I've wired it all up and I'm just waiting to get the windscreen replaced so that I can then install the sensor. However I already have the ch/lh lights working.

    I also have wired up RHM1a4cab a4 cab so that the ch/lh lights work but without the light sensor


    If you don't have a highline module and only have a lowline module then I believe that there is a relay kit that you can buy but I have never fitted one

    Thanks for all the replies,
    ive been going through all your past discussions...mainly between gaz and RMH1.

    ive done the test and my headlights stay on so mine is a HIGH LINE module.

    so im assuming i just need to buy the switch from audi - part 8E1 919 094 A 5PR

    then (ive taken this from gaz's previous response)

    -------------


    0.35mm cable is used and
    Pin 7 of the Ch switch goes directly to pin 24 of the grey 32 pin connector (T32b) on the central electric's module


    Pin 4 of the Ch switch does go to pin 20 of the grey 32 pin connector (T32b), but as you can see that this is linked to the main light switch I found that pin 20 of the grey connector was already used so rather than running another cable I soldered the end of pin 4 cable to pin 1 on the main light switch

    ---------

    is that all in regards to wiring? And exactly what code needs to be put in vagcom? I will be taking this to a local electical specialist who said he'd have a go... im assuming if i show him this he'll understand? lol im useless at fiddly things like this lol

    Is this job done? Or anything further necessary?

    thanks for all the help

    Also is this for side lights and fog lights and can they turn on possibly when i take key out of ignition? As for unlock is it possible to have the option for eg them turning of when i open drivers door or is the timeout only way for them to turn of?

    As regards wiring yes that's it it's 2 connections.

    Yes all you need is the switch there are a couple of variants of switch so just make sure you get the right one

    My car just had the headlight height adjuster switch so I brought the variant that has the headlight adjuster and the ch/lh switch.

    As regards coding you just tell the module that there is the light sensor fitted. It will log a fault that the light sensor is faulty but that's just because its not there you just need to ignore the fault code. It doesn't effect the car at all there is also a coding option to change the length of time the lights are on for but I just left this alone at the default setting

    The front fogs and side lights come on on my car. They come on when you pull the key out of the ignition and go off after a set time after the car is locked. Then when you unlock the car the lights come on and either go off when the drivers door is opened or after the allotted time whichever comes first

    What code is he trying to input.

    You have to change it so the car thinks it has a light sensor fitted,as gaz says it will throw up a fault in vcds but ignore it.

    I can't remember the exact code and i'm currently miles away from my car.

    Its not a case of being too busy, its a case of being in the area, the job alone isn't economical to drive to & do for the day I'm afraid, I think that's a fair POV.

    Don't know why your lights came on but that number is for a lowline unit.

    The lights always come on auto when light switch is removed/disconnected, its a safety mechanism they have, so at least if its dark you have a way to see even if switch isn't working etc.

    Well every car I've ever removed light switch from has turned them on, various chassis, maybe I've avoided specific modules just by pure luck, Jon knows his stuff & I don't like to question him at all tbh as he's usually correct lol, top bloke aswell one I respect highly.

    Yes coding Is just literally just select the light sensor as you have found you have a low line module so the light sensor option is not available

    Swap the module over for high line module which will have a pin 24 and bobs your uncle you will have the feature

    There is a relay kit available I think. someone has linked to it on a previous thread this uses the interior light and takes a feed from there to switch a relay this then switches the fog lights on I think .this method is not OEM

    Or replace the module to go the OEM route but as you discovered it can be very expensive
    Keep an eye on eBay they some times pop up
