Stamsaas he has retro fitted a complete fl front end to his http://www.briskoda.net/forums/topic/229770-the-norwegian-vrs-low-clearance/page__st__90#entry2905870

Wow, that's a serious good project journal, that is one of the best looking vRS's I've seen (green wheels excluded!).

One thing he did mention was that retrofitting a FL front end to a pre-FL is a big job, all the metal that the headlights secure to needs changing too, the BCM on the pre-FL won't power the headlight adjusters and the wiring is all different.

I'd hope that just a bumper swap would be simpler, but on his pictures he definately has the LED DRL's working - so it can be done, somehow!

Thanks for the diagram. It really helps me alot!

I´m doing a "retrofit" of the FL RS bumper to Pre-FL RS. I´m planning to code the fog lights to act like DLR with VCDS and connect the fog light wires to the DRLs. Then make completely new wiring and relaying for the fog lights.

Please, please, please take lots of pictures when you are doing it and post them on here as this is something quite a few of us are interested in but don't have the balls to do!

Ok, i have few pictures of the process fitting it but they are shot with a crappy cellphone camera (have to transfer them to the laptop first). Will get better pictures when parts arrive from the painter and i fit the parts to the car.

I think it´s not the lack of balls, but the money you have to put on the retrofit. I calculated around 1000 € for the parts and professional spay for the parts. I found only the bumper second handed and all the other parts are new. :think:

The reason for my interest is that whilst I'm not going as far to retrofit a FL bumper I am considering OEM LED DRL's.

The Octavia Scout and Fabia vRS use these (see pic) which are a straight swap for the front fogs on the pre-FL vRS.

I too was looking to activate the front fogs as DRL's (using VCDS) and then fitting these OEM DRL's from Superskoda.

The problem is (I think) will be the wiring. The LED DRL's on the FL vRS ahve three wires (as per your earlier post) whereas the front fogs on my pre-FL vRS have two wires, so I'm guessing there will be modifications required to the wiring loom - it is this that is putting me off...

Did a little testing with the DRL´s and i got them to work partially... They work but the LED´s flicker and i get these fault codes:

Do i need to add resistors before the DRL´s? So are those fault codes like the ones you get when putting LED´s to the licenceplate lights? And is the voltage low or should it be more than 11.90 Volts for the LED´s to work properly? I´m thinking that maybe there´s a little dimming done programmatically on the fogs and i have to look on it with VCDS, if i could remove the dimming? Every idea is welcome now as i am no expert with electricity. :think:

LED´s are now working properly but still have those fault codes and the annoying warning lamp on the dashboard. I´ll have to get some resistors and try to find the right one to emulate the power consumption of the fog lights. No easy solution so far but we are getting closer.

Update on this, i got the warning lights off and no fault codes anymore. The connection looks like this:

It is possible to replicate the FL DRL logic but it requires a relay that cuts the power off from the yellow wire when driving lights are on. I got lazy and didn´t do it, so the DRL´s work only when the driving lights are off(Light switch on position 0 or Tunnel mode when theres enough light from the environment).

what resisters did you use

They are 50W and 6 Ohm resistors, one on each side. Had to use a little imagination on positioining them in the car because they tend to heat a little so you can´t attach them to plastic.

Wow. Great posts on this thread. Now I have the confidence to go for the full vrs bumper upgrade.

Unfortunately skodateile had stopped selling the vrs led DRL wiring kit. He would have given me the wiring diagram with the kit too.

That's the only thing I need now.

Any suggestions as to where I can find the led DRL wiring kit?

I'd assume that the wiring loom for the DRL's is the same on both the non-vRS and vRS Octavia.

You need to ensure that your non-vRS Octavia has DRL's to start with. Here in the UK only the Elegance and L&K (option on the Scout) get the front fog / halogen DRL light unit in the front bumper. These models therefore have the wiring to feed the DRL's.

The LED DRL's on the vRS have their own power regulating module built into the back of the unit so the 12V supply will be the same as on the non-vRS models.

So in theory fitting a vRS bumper to a non-vRS Octavia should be straight forward as the wiring for the fogs and DRL's will be already present. Getting them to work in the same way as the vRS will be a different challenge!

If your facelift Octavia doesn't have front fogs / DRL's fitted from the factory then the wiring won't be there and it will be more complicated,

What you also need to consider is that the LED DRL's on the vRS are dual function, they dim to perform the function of sidelights/parking lights.

The non-vRS OCtavia operates differently, the side/parking light function is performed by the traditional 5W bulb in the main headlight cluster. The DRL doesn't dim, it is turned off completely when the lights are on (side or dipped headlights).

The propblem is that the car's CANBUS system is programmed to tell it that it is a vRS and therefore the way it operates the DRL's (dimming) is different to the CANBUS on a non-vRS Octavia where the DRL is programmed to turn off completely.

The standard 5W sidelights are still present on the vRS in the headlight but they aren't wired up.

Whether the CANBUS on a non-vRS can be re-programmed so that it thinks it is a vRS is the 64 million dollar question!

hello, 

 

my car is non VRS FL with OEM Halogen DRL, I have installed the VRS bumper with the OEM VRS LED DRL.

 

I did wire the +ve & -ve wires of the Halogen DRL plug to PIN #3 & PIN # 2 of the LED DRL, but unfortunately it did not work at all... any Advise please?

 

Thanks

To do it properly, you also need to disconnect the sidelights and connect them to the LED DRL.

 

You'll also need to take it to someone that can recode the lighting configuration of the BCM. VCDS can't do this, you need something like VCP or ODIS-e.

Do you think it can work directly from the battery using a DRL relay? like the below diagram?

 

i don't want the dimming function, i just seek for the full illumination during daylight..

 

But what make me wonder is how its connected now to power from the existing Halogen DRL and it does not works!?

I would try connecting pin 1 to power and pin 2 to ground, leaving pin 3 disconnected. The wiring diagram shows pin 3 is only used in vehicles without sidelights, suggesting that if it's left disconnected it'll be at full brightness.

 

However, on the vRS they are connected as follows:

- pin 1, powered when either DRL or sidelights are used

- pin 2, ground

- pin 3, PWM signal, ~15% for dimmed, ~100% for DRL

 

That would suggest connecting both pin 1 and 2 to power should also give full brightness. If you are reusing the existing halogen DRL wire, you should turn the DRL dimming to 100% in the module 9 coding.

 

I haven't got a vRS LED DRL to test with so it would be interesting to which or if both work.

I finally managed to make it works...

 

after several trials, i found out that pin#1 must be connected to live for the whole unit to works...

 

If pin# 1 is connected to live & Pin#2 is connected to ground, the unit only dim...

 

So i did connect pin#1 to switchable live signal, pin# 2 to the my halogen DRL -ve wire & pin#3 to the my halogen DRL +ve wire..

 

Now it works as it should be, while side lights/low beam is on, the LED DRL unit dim only...

 

if the light switch is on OFF position, the LED DRL give full illumination.

 

Thank you for your support
