Any idea on how to get this activated? I tried the codings in Vagcom that I thought would activate it but without success. Greatly appreciate it

Fog light in reverse or Euro rear fog light?
- there should be coding changes in Gateway Module (46)

front Fog light in reverse. I saw something that mentions module in the Central module (I Think) but it didn't work

The rear fog light is another question thread :)

Is the cornering light the one in the headlight, or did you change the cornering light to the fogs?

I don't recall having the fog cornering lights activate in reverse on my old Passat.

You can have the front fogs coded to use as cornering lights. But if you have HIDs in the fogs, that would blow the ballasts very fast.

If you are already coded for cornering lights, they will also come on in reverse when turning the wheels.

Keep in mind that if both headlights & fog lights are on the cornering lights will not work. They work only with the headlights on only.
*This may only apply if you have Bi-Xenons with AFS*

the cornering light right now is the in the headlight. I did not change it to fogs. If I do that, would I loose the cornering light in the headlight? I only did the DRL to Fogs change so far. The reason I ask about the fogs activating in reverse is because of our former 2018 Tiguan before trading it for the Atlas. Both those cars have the fogs activate when I am in reverse.

Yes, you would loose the functionality of the cornering light in the headlight

I was thinking on putting LEDs on the fogs. I do have the Bi-xenons with AFS. But I wanted both option of the cornering lights to be in the headlights and the fogs.

Requires a trigger wire to be wired in to the euro headlight switch before you do the VCDS coding. Available here:
https://www.ecstuning.com/b-genuine-volkswagen-audi-parts/rear-fog-light-trigger-wire/000979009e/

Instructions and more details from start to finish are here:

And the requisite video:

thank you. The video is not working. If I am understanding the thread right, the only modification I need to do is the switch, trigger wires andCECM module by the dash( and coding changes and buying the EURO lights of course). No changing of pins in the connectors for the tail lights. Is that right?

You can splice the wiring so both cornering lights & fogs work when you use cornering. I don’t recommend but you can do that to get what you want.

no, I don't want to do any splicing at all. I just thought both cornering lights and fogs would come on without major mods. Thanks.

Someone on the CC forum figured out the coding process to do it. however though, the CC is on a different control modules architecture than the 06-08 Passats

Actually, they are the same until 2010+, then the CC’s & Euro B7’s run BCMs instead of CECMs.

You can also retrofit/upgrade to BCM as I did. That’s hours of work though.

might be worth a try hehe. Do you have the link to that?

If you have installed the actual euro tail lights that have the amber/red/amber switchback turn signals and the red lens in place of the clear on the left rear backup light, then they will work right out of the box, no pin changes on the tail lights are made. You would only need to use VCDS to activate the rear red fog lamp when pulling the euro headlight switch out to its second position.

If you have a wagon and only want the rear fog and don't care about the amber/red/amber turn signals, then you could just replace the left rear backup light assembly and then use VCDS to activate the rear fog function after installing the trigger wire. Available here:
https://www.ecstuning.com/b-genuine-european-volkswagen-audi-parts/rear-fog-light-assembly-left/3c9945093/

US-spec Passat B6 taillights have just one LED light giving a red turn signal, while the Euro taillights have two LEDs (red/amber) that give the amber/red/amber/red effect, which is actually rather cool. If you can find them, they can be had as either smoked or clear. For example:
For sedans:

https://www.aliexpress.com/item/Euro-Spec-LED-Tail-Light-For-VW-Volkswagen-Passat-B6/1511243333.html
For wagons (clear):

These euro-spec taillights with amber/red/amber/red turn signals are getting harder to find as the B6 models get older. Shop carefully.

Factory Euro-spec tails are red or cherry red with no reflector (R36, as the rear reflector is bumper mounted)
Hella has the cherry red in aftermarket form (with the rear reflector, which I had at one point).
You can also code the which the brake lights are no longer part of the running lights also.


You don't have to get European tail light set for rear fogs. You can get a red 1156 bulb instead, or just the inner section that has the red lens for the rear fog.
