Coming home lights

Yes I read that, the write up is really meant for low line modules, I do think I'm may be missing a single repair wire or something I will get it working one way or another.

The switch was £27.
 
Have you read up with elsawin to check the pinouts correctly, as relying on net guides sometimes missing a few important notes, maybe the reason for issues.
 
I've ordered a copy of elsawin but it won't arrive until early next week, if anyone has a copy could you do a screen grab of the wiring diagram for the ch/ lh light switch I have installed.

Thanks

Simple way to check( as a8 posted in my other thread) is to disconnect the headlight switch and turn the ignition on if the headlights come with the switch unplugged then you have a highline control unit, even with a lowline unit you can still do it but it requires more wiring.
 
i have a brand new highline from a DTM if anyone needs 1

GREEN = EARTH SIGNAL
RED = LIVE 12 VOLT TERMINAL 30



For b6 lowline without fitting a switch just picks up off the interior light open signal and ignition key S contact removal

Not fully completed yet but it gives the basics to convert switched earth to switched live and final output to the fogs

please add any amendments


I just run this set up to test and it works but the fogs will come on when you remove the ignition key as the primary input is the signal from j393 to the interior light, the fogs go off automatically when the dim function of j393 activates so 30 seconds or so

Be careful though i mistakenly gave pin 5 a 12 volt feed and popped the control unit but I have a spare

Sorry to bring this up again, but on my centrl conv 9 mine shows

8E0 907 279M

Does that mean it can't be done on mine? My car has no additional features but I have just bought a DIS stalk, just not fitted it yet.

Thanks

I bought one of the coming home modules off ebay and did it that way. It has a light sensor so it works the way its supposed to.
Its not oem, but works a treat.

Was it a universal one? Seen one on ebay by a company called going fast.how much work was it to install,and how does it work?
 
It was a universal one, I picked it up off a german seller, worked out around £20 iirc including delivery. not to difficult to install, I hooked it up using central locking pulse. So when you lock/unlock the doors at night it lights up front fogs. Also as the car autolocks above 15mph, when you park up and take the key out the doors auto unlock and the system works off that.
It took me a while fitting it at first because I had to find the central locking pulse, but now I think I could do it in less than 2 hours very easy.
I'll dig out the link for mine, it came with english instructions too.
 
This is a mod that I need to do, my friend has this on his golf and it is handy!
 
Emmo,could you tell me where you installed the box and could you tell me where you picked up the connections please.

Looks like a nice simple bit of kit.

Many thanks

Tony
 
Tony,
if you drop the panel under the steering wheel, you have access to the fusebox.
You can pick up earth and +12v from the terminals under the dash from here too.

Two bolts hold the fuse box in and if you pop the back of the fusebox off, you can splice the output from the module to which ever lights you want to light up. I went for the front foglights as they light up your path very well.

Then you need to run two wires from the unit (+ve central locking pulse iirc) along the sills and into boot panel on the right hand side and splice into the connector which comes off the connector which locks petrol flap. One wire does unlock and the other does lock ,splice one wire to each one.

Connect up the light sensor to the box and run the wires along edge of dash and position where you want the light sensor, it looks just like an LED. I have it sticking up at the corner of the dash on inside of windscreen. The wire is pretty thin an easily tucks down the edge of the dash.

I taped the module up under the dash and tidied up the wiring. Put the fusebox back into position and put the trims back underneath the dash.

If you need any more info give me a shout.
 
thanks for that,with regard to the connctions to the fog lights,did you splice into the cable at the switch or run cables done to the light unit?

just ordered the unit from the link above,worked out £18 at current exchange rates.
 
I spliced into the foglights +ve at the fusebox.
 
while those descriptions anwser about 90% of any queries i would have any chance you could take a couple of Pics of where you have spliced the wires in the fusebox and at the filler cap?.
its just one of those ones where a picture saves any "silly mistakes" plus that combined with couple pics would be a decent "how to"
 
I should really have taken pictures! To take pics now I'd have to take panels off , remove boot panels and remove fusebox etc. A bit of a hassle really.
it really is fairly straightforward, and I will answer any questions best I can.
 
fair enough, though it may have been a 2 min job, for couple pics.
If any one else is doing this fancy taking a couple pics so that they can be marked up for wires etc and made into a " How too"
 
Emmo hi,i received my box this morning and reading the install instructions,the instruction ask to cut and reconnect the box between the light circuit ie cut the l/h light feed and connect yellow and yellow/black from the box to the cut wires.if so are the l/h and r/h light cables behind the fuse box?

many thanks tony
 
Theres no need to cut the wires I just used a scotchlock and tapped into the foglight wires and connected to the output wires off the module.
In the fusebox there are two wires for the foglights, both are white with blue stripe iirc. They join at one end of the fusebox and split off to the relevant foglight. It maybe fuse 15, but double check that before you start.
I read the fusebox diagram the wrong way round initially and tapped into the wrong wire and was scratching my head wondering why the foglights werent working.
 
Tony take pics....... apologies for sounding like a broken record but would clear this up for me a bit more with regards to what wires are spliced and where. even if its just pics of the actual splices for wire colour refrences.
 
ok,i managed to get the box fitted this morning,not as straight forward as emmo's instruction as our car wiring seems to differ.I dont have fuses for the fog lights,my lights are controls by J519 on board supply unit.All turned out simple after i printed of the circuit diagram from elswin.

First the box


Box
then the contents

then the insructions

Instructions


As Emmo said,run a 2 core cable back to the fuel flap solenoid,i did this first before having to get wiring diagram out so i sure i could of found the connection closer to the dash but it was to late.i cut and crimped butt connectors to splice into cable the colours seems to be the same,grey with a mauve trace although one trace seems darker but i found it didnt matter how you made the polarity because the box is looking for a pulse to do the same thing when you lock and unlock the car.

Fuel cap lock

Fuel flap lock


You can follow emmo's note on how to drop the cover under the steering wheel and how to remove fuse box, pick up a 12v supply, and ground,connect the 2 core cable to the two brown cables,install the light senser where you like,i installed mine at the side of piller and dash board down by the window screen.
my light are controlled by the onboard controller(J519)
Under the steering wheel you will find the box with the relays on top,under the box you will see the 23 pin black plug,you can unplug this (ignition off)with out problems.Pin 19 White/Blue is for the Right Hand Fog Light.Pin 21 White?Green is the left hand fog light.
The instuction ask to cut and connect yellow to light switch and connect yellow/black to left light,before doing this i checked for continuity in the box and it had continuity,so i did follow instuctions as to cut and connect the output of the J519 through the new box.I did the same for the right hand light,again i used butt crimps incase the box fails to make it easy to revert back.


Connector
Box works a treat.


No bulb out warnings,fogs work ok,fogs also flash when locking and unlocking in the day time.

Hi Tony

Might be throwing the cat amounst the pigeons Here but is that a picture of your central electrics? J519??

If so can you just confirm that the part number ends in N it looks like it from the photo ?

If so you can get the Audi oem ch/lh working by just adding a wire. That's what I did with my cab

Good job tony! Glad you got it sorted. Its not bad for £18 and couple of hours work is it.

Gaz would the car not need to have the mirror with light sensor in for this to work? Wouldnt the coming home lights come on even in the day otherwise?

Hi Emmo

Yes you are right I am half way through retrofitting the whole system just need to change the windscreen but at the moment the system is working as you say.

The lights come on and off when you open/lock the car yes they do come on all the time but the car seems happy with that.

The only thing that happens is when you scan the car the central electrics module comes up with a fault saying that there's a fault with the light sensor.

That's obvuisily because its not there.
It doesn't affect the car though

So yes technically you need the light sensor but the system works fine without. It just works day or night.

Mines all wired and ready to go I just need to get the windscreen replaced and clip the sensor onto the window

But for now I'm happy with the lights coming on day or night
 
A big thanks to Gazthesparky for sorting coming home lights today, great job, working perfectly.

Thanks
 
It just proves it can be done with a few wires and a better understanding of wiring diagrams than me. :D
 
Can this be summarised up by saying that if you have a highline module and are prepared to have the lights come on even if its not dark - then ground pin t32b and encode and adapt j519 address 09 for the function.

Cheers

Chris
 
Hi
i have the J519 module ending in N- whats involed in enabeling them?
I am not fussed about them coming on in the day time and night
 
Gaz has just done mine., if you have a highline module (ending in n) then all you need is two repair wires, Gazthesparky will give you a far better description of where they go, but it only took him about an hour to fit. He made it look very easy.
As you say it works day and night because there is no sensor fitted but I'm fine with that.
