W203E35

Hey guys,

So I was playing with DAS and did a setting and now when I make a turn my fog light turns on and then off. WTF is going on? This is what I did.















This is a DIY on how to enable Cornering Fogs on your 203. The first time I saw these were on a 204 and I honestly thought the fogs were malfunctioning until my friend told me it's a feature. We have always had this feature but it was never enabled.

Also if your DAS menu doesn't have this let me know and we can do it through Developer Mode

Happy Cornering,

Karo

Wait, so the fog lights adjust for your cornering, but they have to switch off first and then turn on again?

Basically when you make a turn one stupid fog turns on to light the area (atleast thats how it looked) looool

If it does that whats the point? it lights like 5 feet into the headlight pattern and then is lost in the bright light, how does that help do anything? Sounds like a badly implemented replacement for having peering headlights.

I had the active fog light function activated on my car. With the normal fog lights it doesn't work all that well as the light pattern isn't significantly better than the OEM Xenons.

From what I've read if you have the OEM w203 active fog lights you get a different fog light lens that throws a far wider beam off to the side. I had a rental Israeli-spec Honda Civic awhile back with Xenon lights and the wider beam fog lights and they made a big difference in turns at lower speeds.

So far I haven't been able to find the wider fog light lenses in the ETK.

I believe these were actually an intended option, not sure if any model years got them. I'm pretty sure none of the sport sedans had the feature enabled, but for some reason I thought the luxury sedans with lighting package had it. Not sure. Anyway, here's a thread with some more info.

I do know other models absolutely had this feature, one that I remember off the top of my head is the CLS. Yes it looks like one fog light is out when you're using it. I don't think it's very functional however.

I had Sunil enable them on my car, and it really is a worthless option when equipped with Bi-Xenon's. Plus, I have had co-workers tell me I have a burned out fog light when they see me pulling into the parking lot. When I get my STAR system, I will disable them. Actually, the fog lights are worthless period. I will be swapping them out with HID's at some point.

Eric is right, the luxury 203's had these enabled with lighting package.

Hey John, you can adjust them up and they work a lot better. You will need a super long phillips head screwdriver. There's a hole to towards the center of the car from each fog light. The glass does NOT move up and down, just the lens inside the housing.

omg its nate

Hmm I am not sure about this mod. Install my HID fogs this weekend. Can't wait!

But honestly, I don't even think they work well on the new 204s eighter. When I first saw it, it really looked like the fog was malfunctioning. It didn't look like it lit up the area well.

It works well on the S, but it's not a fog, rather another light all together.

i see, as mentioned earlier our fogs are more for cosmetic I believe. Not really that great

We have this feature enabled with the stock Bix - I had exactly the same feedback to my wife the first time I saw it. I thought I had to replace a foglamp bulb because it was burnt out.

I'll give that a try Eric, but I still have a feeling the W203's fogs just aren't very good.

I think the problem with our US-spec w203s is that we have the wrong fog light housing to take full advantage of the active cornering light feature.
