FABIA NJ 2015+ FRONT FOG LIGHT RETROFIT GUIDE

 

                                                                                                                                      

 

 

After looking around on this forum there wasn't any guide or info on retrofitting fog lights into the Fabia III (NJ) - The only posts I could find on here was this post back from 2017. I went to order the kit mentioned in that post. (6V0 052 186) But its discontinued. TPS and Skoda both said this item was not available even from 'Germany' 

 

I did some googling and found two sights selling the kit. (NOT UK)

 

Link 1 - https://www.skoda-parts.com/spare-part/6v0052186-retrofit-kit-halogen-fog-lamp-oe-24655.html (I ordered mine from here and didn't encounter any import fees post Brexit) (NO LONGER AVAILABLE) 

The Skoda Kit has been discontinued so moving forward you will most likely need to source the parts yourself or purchase a pre made wiring loom off a site like AliExpress.

 

The kit came with instructions but for LHD and only for the kit itself so I decided to produce a guide for RHD vehicles with pictures to help, also the guide lists all of the Part Numbers needed to make your own kit up if you cant source a Skoda kit.

 

**If making your own kit you will need to build the wiring loom yourself and measure out the distances of wire needed as I used the pre made loom in the kit, I have included a basic wiring diagram for this) I would estimate around 5m of each wire would be more than enough to produce a wiring loom***

***THIS IS A GUIDE AND YOU DO THIS RETROFIT AT YOUR OWN RISK, I WILL NOT BE HELD RESPONSIBLE FOR ANY DAMAGE CAUSED DURING INSTALATION OR CODING. PROFFESIONAL INSTALATION AND CODING BY A REPUTABLE GARAGE OR MECHANIC IS ALWAYS ADVISED***

 

PARTS NEEDED

 

6V0 052 186 – Front Fog Light Kit (Discontinued but can be found in Europe)

 

Here Is a list of the individual parts found in the fog light retrofit kit (Since I used the Skoda made kit my wiring loom was premade, I wont be able to help you make it but I have included all the parts + diagram below to build your own, Green wire is for the left N/S fog, Blue wire is for the Right O/S fog and Brown is for ground)

 

·         Left fog light – 6V0 941 699

·         Left trim for fog light – 6V0 853 665 (9B9)

·         Right fog light – 6V0 941 700

·         Right trim for fog light – 6V0 853 666 (9B9)

·         4 x hexagon socket head panel bolt – N 10412804

·         2 x Halogen bulb – N 10529501 (H8 12v 35w Bulb)

·         2 x Bulb plugs - 3D0 941 165 A (Some come with pre-installed wire tails)

·         4 x pins for bulb plugs - 000 979 244 E (With seals)

·         This is repair wire so you will need to solder the pins onto new wire as this is only repair wire.

·         1 x crimp hoop for ground strap (8.5mm and up)

·         2 x pins to connect to BCM - 000979025E.

·         Felt tape and 7mm polypropylene solid conduit to protect the wires.

·         Cable ties

·         Trim clip cable tie - 3D0 971 838 E

·         Silicone sealant

·         Green / White wire

·         Blue / White wire

·         Brown wire

 

As well as the kit you will need a new rotary light switch.

 

Rotary light switch with fog light (Auto model) – 5E0 941 431 D  / Rotary light switch with fog light - 5E0 941 431 F

 

This will only work on cars with BCM Control Units – 6C0.937.087 - 6C0.937.088 - 6C0.937.089

If you have BCM model 6C0.937.085 then you will need to order higher series of BCM control unit with Part Number 6C0.937.089 from ETKA (TPS or Local Dealer)

 

*** YOU WILL NEED TO RECODE THE MODULE. I AM NOT RESPONSIBLE OR HAVE THE KNOWLEDGE ON HOW TO RECODE A BCM SO PLEASE DON’T ASK***

 

***************************************************************************************************************************************************

 

INSTALL

 

Firstly, open bonnet and disconnect the battery.

 

Remove lower grill blanking covers in the bumper where the fog lights are going to be installed.

 

 

Remove wiper arms and water tray / plenum cover. You will need to use a flat head screwdriver to remove the washer jets wiring from the side of the water tray

 

 

Behind the wiper mech you will see a rubber grommet with a nipple and a tab on it. Cut a slit in this rubber nipple for the two BCM wires to be passed through. (Do this first so you then know you have enough wire to plug into the BCM. (You will need to use the silicone sealant to reseal this hole once installation is complete to stop water ingress.

 

 

Make sure to pass the wires underneath the wiper mechanism so that the wires do not get in the way of the wiper mechanism. There is a plastic ring to the left of the wiring that you can pass it through that keeps it neat.

 

Once you feed the wires through you will see the wires appearing through the foam duct above the driver’s pedals. (I had a friend push the wires through till I was able to grab them and pull them through myself.  Picture bellow with the circle around it is where the wires will come through. Pull through around 25cm of wire.

 

 

Once you have pulled the wires through you need to remove T46B (Brown middle plug) from J519 (BCM) Lift the white tab up and the brown plug will slide out.

 

 

 

Once unplugged you will need to remove the black and brown plugs from the brown plug. They have small little clips that hold them in place on the outer edge of the clip.

On the inner plugs they will have the numbers for the relevant pin holes.

 

Plug the corresponding wires into the corresponding pins.

 

Green / White Wire --> BCM Plug B / Pin 40

Blue / White Wire --> BCM Plug B / Pin 3

 

To reconnect brown plug, do the reverse of removal.

WIRING INSTALL - ENGINE BAY

 

Here is a diagram to show you how the wires are run through the engine bay.

 

 

This is a diagram for making your own loom, use plenty of cloth tape / conduit to protect the wires. The ground wire is the only one that will need a split to go to each light. Green and blue can be one continuous wire

 

 

 

Run the wiring loom down the left hand side of the engine bay (looking at windscreen) under the foam, tuck down the side following the existing wiring harness, towards the front O/S headlight

 

 

Cable tie the wiring loom to the existing loom by the AC sensor and headlight plug. (not tight as to allow the harness to move freely until installation is complete)

I found that removing the headlight plug allowed me to tuck the harness under the light.

 

This is where the wiring loom tees off to the O/S fog light and the remaining wires run over the radiator to the N/S fog light. Unclip the washer fluid neck and runt the wires behind it.

 

 

 

Use 3D0 971 838 E to secure the wiring to the trim pieces / radiator and use existing wiring securing points along the way. I used a total of 3 cable ties across the radiator.

Run the wires underneath the top radiator hose towards the N/S chassis leg. Where you pass the wires over the leg down towards the N/S fog light.

 

 

Connect the grounding loop over the existing grounding strap found on the outer edge of the chassis leg, access this through the empty fog light hole In the bumper.

 

 

You should now have two sets of wires dangling in the open areas of the bumper. Ground sound (N/S) you will have a Green/White + Brown and O/S Blue/White + Brown.

 

 

Plug the wires / pins into the 3D0 941 165 A plugs.

 

N/S – Left hand fog light

·         Green/White Wire – PIN 1

·         Brown Wire – PIN 2

 

O/S – Right hand fog light

·         Blue/White Wire – PIN 1

·         Brown Wire – PIN 2

 

Once the plugs are built on both sides you can plug them into the H8 Bulb located on the back of the fog light. Seat the fog light into the bumper and secure using the two hexagonal fixing bolts - N 10412804

Then place the new grill and push into place, this takes some force.

 

 

Go round and fully secure your cable ties. Use your silicone sealant if you have not already to seal up the rubber grommet behind the wiper mech before re installing the water tray and wipers.

 

Before you close the bonnet, move into the cabin, and remove the old light switch by pushing in the light switch dial and twisting clockwise, this will release the switch and you will then be able to pull it out and swap in the new switch. – do the reverse for install.

 

 

Now reconnect the battery ready for coding.

 

 

***************************************************************************************************************************************************

CODING

 

Once in your preferred diagnostic software navigate to 09 Central Electrics.

 

OBD11 – Long Coding, Tab 2 (little family) scroll down till you see ‘Light Switch with front fog lights’ click on this and change the following – Not Installed --> Installed – Swipe to write.

 

***If someone could confirm this -  I believe the long coding to activate light switch with front fog lights is as follows - 09 CE – Long Coding, long coding helper – Byte 7 bit 3***

 

Photo from @wirer's VCDS Guide. (Thank You)

 

Once you have told the car the light switch has been installed, you will see that when you pull out the fog light switch the front fog light symbol appears in the dash cluster.

 

Navigate to the Adaptations and locate both the following. Once found change only the settings listed below.

 

/// Leuchte12NL LB40 ///

 

Type of Load 12 (lasttype)

 Nicht Aktiv --> Allgemein Scheinwerfer

 

Light function A12 (Lichtfunktion A12)

Removing Sales links due to issues / products no longer available

[ChalmersCameron]

This is great! Wanted to let you know that second link listing the kit is sadly a scam, so it may be worth editing to remove it!

 

I ordered from there and it's been nothing but hassle, and the reviews online confirm it 😞

Thank you @ChalmersCameron for bringing this to my attention. - That's not good at all and I will remove the link asap as that's not cool at all. 

 

If you've not received the parts I would advise contacting your bank if you didn't use PayPal. Sorry to hear of the issues. Its never nice to hear. Hope you can resolve it soon and you're able to come out with a good outcome.
