Right... i've done it!

Managed to get this working on my felicia!

It can be done without an auto headlight controller but I have wired it up to this.

Basically here is how I wired it up:

relay:

Permanant live to pin 30 and 85

Pin 87 to switched live on the auto lights controller with a diode to stop voltage leaking back into the switched live in the car

Earth from the door lock switch to pin 86.

So basically as the doors are unlocked there is a live supplied to the switched live on the auto headlight box which then turns the lights on after a short delay.

Now working on a deactivation switch on the dash which will be a second sidelight switch in the blank space.

where can you find out about all these extra relay kits? just wondering what extra ones would be available for a mk2 octy?

I'm afraid that I made comment about the existance of various retro-fit kits being "not widely known about within the VAG parts dealership" - and only coming to light as NOS being sold on Ebay but got shot down by someone who thought they knew better!

That's a really useful mod and something I'm interested in but I have a question. As you have linked to the light switch module, does the lights on warning buzzer come on when you open the door to exit the car?

Also has anyone managed to fit some kind of timer to this circuit so the sidelights remain on for a specified time?

[Akshay]

Does this mod cause the lights on warning buzzer to come on???

There isn't one. It's only relevant for cars fitted with the later CAN interface. So perhaps it could be done on the Roomster/Fab Mk2....

Thanks for the reply on which lights come on Rich. I only wondered as I wouldn't do the same myself, as I have xenons and wouldn't want these coming on every time :) And thinking what Mercedes do in particular with their system, when the side and foglights illuminate.

Steve

the option is in Vag-Com but just to confirm the roomster has not got the controller to allow it, so it could be expensive to do or indeed head the way that Fab 12V has if it was needed.

Don't know about this version, but the factory relay does not activate the warning buzzer (someone mentioned that in the other thread I linked above).:)

Ideas to play with -"slug" relay  with reverse potential diode or with a big electrolitic capacitor ( of sufficient voltage rating ,connected correct way round,else BANG)
OR if that fails operate power relay via suitable smaller relay,slugged as above .(Capacitor slugs -case  of suck it and see -lot depends on sizeof capacitor and resistance of relay -time constant circuit ,in that capacitor charges( to 69%) in CR seconds ,and also can be assumed to lose charge at the same rate )
If interested in idea -read up on time constant circuits .
Going back to ancient times,there used to be dozens of electronic 555 circuits to do this ,but electronics may not be everybodies cup of tea -hence initial ideas .

Not so much of the ancient times there 555's are still around,cheap and dead easy to setup,
If you want to really go back in time try building monostables with discrete components  (carbon based resistors and to5 can transistors) and getting them to work accurately and consistently on a repeat basis!  or if you are really wanting old try valves! (tubes to you younger guys)

Ive got a mk4 golf and really like this feature. Has anyone figured out a way to get it to work but without the annoyance of the lights coming on every time somone opens a door? i.e has anyone got it working flawlessly like its a factory feature?

Thanks.

[suze]

I might get brave and try this! :)

[pip_vrs]

Did anyone fit this to the mk1 fabia and get it working 'perfect'?

[TriggerFish]

I got it fitted on mine (no remote locking, but same apart from that) following the guide.

Anyhoo, the biggest problem is it turns on whenever you open a door - really annoying when you drop off/collect passengers or get something out of the car. What I was wondering is if it's possible to wire it into the door locking - so when the locks fire it switches the relay, but I'm not sure how they would turn out again that way as I imagine they will only turn off when the locks activate again.

Also - you can't easily use the sidelights as they are wired for left and right, and not as a pair (I assume cos of the indicators acting as parking lights).

All I can offer I'm affriad.

[pip_vrs]

Cheers for your reply mate.

I'm thinking wiring it as the first post but putting a diode in series with the interior light, this would stop the 'reversal' and stop the lights coming on with the interior light in normal use??

does anyone have the wiringdiagram? i could do it easily then

Cheers

[TriggerFish]

No idea on the diode - but I can get the wiring diagram up by this evening with any luck.

Joe

[pip_vrs]

cheers mate that would be great

[TriggerFish]

Here you go, if they're not clear enough/wrong ones let me know and I'll try again.

Thats the key from the Haynes manual they came from if it's needed at all although it's not very clear.



And the left is the interior lighting C.D which I think should be the right one.

Think i'll buy a haynes to see it better.
I'm gonna give this a go when i have time and it's a bit warmer.

[Ryan90VRS]

wish i had the minerals to do this to my car, i'm a bricky though not a sparky.

[Richie___vRS]

Would it be the same principles if I wanted to hook up the interior light to the sidelights and fogs?
Just another relay for the fogs.
Really interested in doing this myself. But don't want the headlights coming on just subtle sides and fogs.

[TriggerFish]

Sort of. It's worth noting that the fog lights won't make the buzzer sound, but the side lights will. You'll also need a connection of each set of side lights (left/right). Not sure if you'd need a relay to do the side lights too, or if the one for the fogs would have the power to run both.
