    Cool Auto lights/wipers/dimming rear view mirror & CH/LH install complete!

    Well it's been another long install. Collecting parts, reading other threads on the subject and generally pestering Ash187 for info but i've finally finished my Auto-lights/wipers etc install! (Well apart from some trim for the rear view mirror).

    I had the new screen fitted on friday afternoon by Peter from windscreen replacement cost, price list to view online. He's been fitting windscreens for 20+ years and i'm really pleased with the job he did. So if you're looking to do this and can't wait for a stone to chip/crack your screen I can recommend him.

    Some pics:

    We had to dodge the rain to get this done. Luckily, once the old screen is out, it was only about a 10 minute job before the new one was in.

    I went for a screen with the slight grey tint at the top.

    The mirror is off the A3 cabs and the TT I believe. Might swap it for the A3/S3 one at some point. This one only cost me £25 off ebay though. As you can see, I still need the trim pieces to hide the wiring.

    Not had much chance to play with it but it seems to be working. Set the switch to 'auto' covered the sensor and the lights came on. Uncovered the sensor and a few seconds later the lights went out.

    I'm sure this install will scare a few people and it is quite involved. As long as you know which end of a soldering iron to hold it's not too bad though. I used a loom from Kufatec which made life much easier.

    Need to find some tunnels to go drive through.

    Oh yeah, and a big thanks to Ash187 who was a massive help answering all my questions!

    Glad you FINALLY got it sorted lol!

    Just a heads up, when it starts raining in the daytime the headlights will come on but from inside the car on the light switch you will only notice the green sidelights icon light up. It doesn't light up the ambient interior lights as it still knows that it's not dark enough for it, don't get thrown off by it... It does sometimes have a mind of its own and light up the headlights when you dot exactly need it but it's a great mod!

    If you look at the first pic you'll see the old screen propped up against the wall. I think you'll agree it had lost "most" of its value!

    Thanks. Still undecided myself but I dare say I won't find an A3/S3 one for £25 so I think i'll leave it.

    I think i'll stick with it for now. Just ordered the trim to finish off the install.

    After a couple of days with these widgets i'm finding that the light sensor is not sensitive enough (lights come on too soon) and rain sensor is a little too sensitive. I've been looking through VCDS to see if I can change their sensitivity and came across the following:

    Light activation threshold. This sounds like if I could turn this threshold down a bit it may do what I want for the light sensor. However, the only option seems to be to make it more sensitive.

    light_thresh.jpg

    Then there is the 'light sensor correction' factor. I set this to the A3. But maybe using one of the other settings would make it more sensitive?

    light_correction.jpg

    Then there is the 'rain sensor correction'. Again maybe selecting another one of these may do what I want. Anyone any ideas?

    Having just completed the same MOD a couple of months ago. I agree that the light sensor is not sensitive enough (lights come on too soon) However, I found the Auto Wipers to be OK!

    As I don't own VCDS myself (I know I should!) I'll be interested to know your findings or recommendation’s or any if anyone else can shed some light on this?? ;-)

    ASH187 I seem to remember seeing a thread you put up about a similar issue some time ago. Did you get any where with it??

    Cheers,

    Ni I didn't really change it in the end as you can make it more sensitive but not less. I have just learnt to live with it and honestly it's not that bad... Especially as I have a set of lovely 8000K xenons in there

    Appreciate the reply Ash, I might have a play at some point when I get my act together & get myself VCDS!

    I remember I changed the HIDs on my RS 6 only because one of the lamps failed, so I thought I'd go from 4300K to 6000K although they looked a lot better & were a closer match to the Mugello Blue paint work of the RS the actual light output was considerably reduced!

    In the end I went back to the 4300K only because they were better for driving around the county roads where I live.


    Cheers,
    Rob

    Yes, rain sensors are based on the principle of total internal reflection: an infrared light is beamed at a 45-degree angle into the windshield from the interior — if the glass is wet, less light makes it back to the sensor, and the wipers turn on - SIMPLES!

    Ok, here is the data I collected & used on MY2008 pre facelift S3 to add Auto Lights & Wipers with CH/LH lights.
    Luckily it seems that the Kufatec wires now come with English definitions printed on them, which is a grate help.


    ~ Auto Lights & Wipers – Wiring ~

    Auto dimming interior Mirror
    Kufatec wire “Ignition Plus” > Fuse 4 in fusebox 5A Fuse (Solder)
    Kufatec wire “GND”> Earth
    Kufatec wire “Backup Signal” > Pin 1 12-pin connector, black (B) Vehicle CE unit (T12c/1)
    or A3 8P3 from MY2010: Connector (C) Pin 28
    Kufatec wire “Signal Loom” > Interior light Pin 6 (Solder)

    Rain and light sensor
    Kufatec wire “Steady Plus” > Fuse 16 in fusebox 10A Fuse (Solder)
    Kufatec wire “Control (Lin Bus) Loom” > Pin 3 8-pin connector, black (F) Vehicle CE unit (T8h/3) (Solder) or A3 8P3 from MY2010: Connector (B) Pin 33

    Light switch (1 x additional wire is needed & 1x 000 979 009 - Repair wire needed) -
    Pin 2 10-pin connector, black (A) (back of light switch) (T10e/2) > Pin 14 16-pin connector, Black (E) Vehicle CE unit (T16a/14)

    Coming home button (3 x additional wires is needed & 4 x 000 979 009 - Repair wires needed) -
    Pin 1 6-pin connector, black (C) (back of light switch) > Earth (Solder)

    Rain & Light Sensor Coding

    For coding just go to central electrics module and on the very first page of the long coding helper
    (byte 0) there is a bit that you need to tick saying 'rain/light sensor installed', tick that and you’re done.


    Coming Home Lights Coding

    Open 09 - Cent. Elect. and select Coding, then Long Coding Helper.
    Check Byte 00 Bit 5 and Byte 00 Bit 7.
    Close out and select Do It to write the changes.
    Next under 09 - Cent. Elect. select Adaptation
    Channel 01 is the number of seconds you want the coming home to be active - 0 to 120.
    Channel 02 is the number of seconds you want the leaving home to be active - 0 to 120.

    Excellent details Rob. Thank you.
    Unfortunately my wiring loom is not labeled. Do you happen to know the pin-out for the interior mirror connector and sensor connector?

    Extracted from one of ASH187's posts:-

    According to ELSAWIN the pins should be:

    Mirror
    Pin 1 > Fuse 4 in fusebox.
    Pin 2 > Earth
    Pin 3 > Pin 1 12-pin connector, black (B) onboard power supply (underdash, drivers side)
    Pin 4 > Pin 1 20-pin connector, black (A) Driver door control unit and passenger door control unit
    Pin 5 > Pin 10 20-pin connector, black (A) Driver door control unit and passenger door control unit
    Pin 6 > Not listed (this is the wire from Kufatec with Innenleuchte (Interior light) that has a pin on the wire)

    Rain and light sensor
    Pin 1 > Fuse 16 in fusebox
    Pin 2 > Earth
    Pin 3 > Pin 3 8-pin connector, black (F) onboard power supply

    Hope this helps?

    As this requires replacement of the windscreen, does anybody have the Audi part numbers of the glass with the bracket already pre-installed? With sunstrip options? Thanks.

    If your lights stay on its a problem with wiring or hardware. The lights stay on to show you an error. Have you changed the light switch at all?

    Thand you for your answer.

    Yes i change my switch for a new one with Auto Position (Facelift model with Cominghome).

    With VCDS in measuring block I checked the switch and all seems ok with the different position (the car see the Auto position)

    When I put 0, light is off.

    i was going to do this mod with the correct audi parts but not sure how it works with a 2009 with drl ,the light switch has drl option where the auto should be . i do have an aftermarket solution though just haven't had chance to look at it but it is "supposed" to offer auto lights and wipers with the equipment already fitted.

    Yes sure.

    It's the same as this one: http://www.a3forum.fr/uploads/upload..._IMG_02491.JPG

    And my car is a pre-facelift (April 2008).

    What's the part number of that light switch? Also did you add the wire from the light switch for the auto function to work?

    That's great! Maybe it was something you coded incorrectly?
