135i question: fog light wiring?

[kbimmer135i]

yes, it's been asked and explained multiple times why there isn't fog lights on the 135 but since they build 128 and 135 together, do they use the same wiring harness for both 1er? but they just don't put the fog lights in the 135?

so basically, do you think that the 1er wiring harness are all the same? if the wiring harness is the same, they just don't put in a fog light but the wires are there.

No front fogs means bigger brake ducts for the 135i

[Dan203]

I'm pretty sure the reason they don't put the fog lights on the 135i is because the oil cooler is down in the space where the fog lights would be. If you tried to retrofit the fog lights then you'd block the cooler and your turbo engine would overheat a lot more.

You both missed his question. He knows why there are no fog lights. He wasnts to know if the wiring harness is the same...there fog lamps could be added. In reality, BMW could have put the fogs elsewhere to not interfere with the ducts. They just cheaped out.

As for fogs, I still can't believe the US 135i has everything for the rear fog lamps less the proper switch. The only explanation to me is that BMW thinks the US public isn't smart enough to know when to use them. Hell, they're probably right.

Do any of you guys ever use front fog lights much when you have a car with them? I have them in the E92 and I haven't used them once. If they were gone I could care less.

You can have your rear fogs work without buying the Euro switch. I tried the mod and it works fine. You just wont have the fancy button with the picture that lights up. This should work on the 1.

Check out this thread:

If you look at page 3 post 65 you will see how I did it using a cap to a super glue bottle.

On a side note, since I did this mod I have never even used them in any real practical sense but it was fun to try to do.

Good luck. If you try it and have any questions PM me. :thumbup:

Thanks for the clarification. Yes, I know darn well the reasons why there isn't a fog light but I was just wondering if the wiring harness is the same as 128i. not that I would add the fog lights in but if anyone ever figure it out, that'd be kool.

I did get the euro switch for the rear fog lights. I just felt it'd stand out and it's for safety reasons. There's a lot of fog here in San Francisco... that's why...

I wouldn't do it. That's the intake for the oil cooler, and the brake cooling. It's one thing to effect the brake cooling, but to effect the engine cooling.. that's bad, and IS the reason why the 135i doesn't have the foglights (M3's don't have them either, btw).

This has absolutely nothing to do with "cheaping out".

it's ok. it's easy to assume that there's only guys on this forum. not a lot of girls are into cars or would post on forums.

I'd have to disagree with you on that one. Obviously, the inlet is a MacGyver job done by the folks at BMW. A non-"cheaping out" way to do it would be to properly engineer a revised front end that would allow for both the inlet AND foglights. The fact that they did not do that only leads one to one conclusion. And it's not that they deleted the fogs for weight savings.

I'd probably agree with you, but do you think the M3, M5, M6 or the Z4 M Coupe & Roadster are "cheaping out"? Look at their front ends. None of the M offerings have fog lights. The only other current model in the US that doesn't have foglights is the 135i. Coincidence? If they were "cheaping out", the 128i wouldn't have them either.

We should all be so lucky as to cheap out like that! :biggrin:

I guess I'd say that they have different priorities than I. Personally, I've used the fogs on both of my cars, and really wouldn't want to own a car without them. Which is a problem, because I can't really see anything integrating even semi-gracefully into the front facia of the 135.

It's just an odd thing to have what I'd call a safety feature on the lesser models, then remove it on the cars that could probably use it a little more, esp. with daily driven cars like the 1 most probably would be for most people. I could learn to live with this deficiency, I suppose... :wink:

[mateo]

They may be the same, but they are wired different up at the front of the car. Because the active turn lights are moved to the center high beam lights on the 135i, where on the 128's they are the lower driving lights, like normal.

Incorrect, the corona (halo) rings around the headlights are the fog lights...!

My 135i has the front and rear fog switches and when depressed the yellow and green icons appear in the dash. The rear light up correctly but of course there is nothing in the front.
I've taken a long hard look at the front air ducts and have contemplated if I could drill 3" holes into them (of course take the front grills off) and then mount smoked 3" fogs into the holes (basically stealth looking). It would not constrict the air to the brakes or turbo but would provide a little bit more light for night.
My question is... if the 128 fog wiring harness is the same then where is the mystery mating connector on the 135i? Is it tie wrapped somewhere behind the air duct or up under the front bumper assembly?
thanks,

Huh, US-spec cars are not even supposed to have the rear fog light switch and you got two? Post a pic. Is it a second-hand car?

Euro versions have only rear fog switch.

And in my opinion they are not worth the hassle, especially if you got xenons. Your car has an additional oil cooler on the right side, I would not put anything in front of it. Just code euro AHL and buy some Osram Nightbreakers and you're golden.

The wiring harnesses are probably different. Because IF the fog light connectors were there on a 135i... you would have a CIC bulb error check light.

A friend of mine with a "tuned" 120d e82 coupe... did a fog light delete(he wanted to look like a 135i ) and he kept getting error codes for his missing fog light bulbs. In the end he couldn't code them out - so he reconnected the fog bulbs and "plastic bagged" them.


IF more better light is your goal... why not just code your headlights to the European output ? Low speed bulb pattern is better and high beam output is much brighter - since US DOT limits high beam output in the states.

I have front and rear fogs on my Mercedes and never use them.

I wouldn't put them on, since there really isn't any room to place them. Well you could roof mount them I suppose?

Is the wiring there? Probably not. If it is, there will be a relay dedicated to the fog lamps. All that's needed is a wire from the relay to the lamps which won't be there. On my Mercedes, the headlight switch contains the switching for the lamps.

Now that winter has arrived in Ohio, I quickly discovered my fan motor was chirping / squeaking from time to time and barely still under warranty. While at the dealer, I asked one of the techs about the fog light wiring harness (if the 128i and 135i shared the same) and he did not know so he removed the inner fender well and confirmed that the fog light wiring was not there. Oh well, it would have been nice to already have the wiring in place but it now looks like I may have to run my own wiring and relay back to the main switch. I'll post some pics when finished (weather permitting first).
