I am writing from Singapore, and my ride is a E90 323i, yr 2008, with Idrive and Foglight (SA520). I'm a DIY enthusiast

I purchased this retrofit kit 63 13 0 414 592 (from Crown Auto), which is a Cornering Light retrofit. As I do not have Dynamic Xenon, I thought that this Cornering Light would be the next best thing to provide some additional illumination in corners.

The EBA is attached.

Installation was relatively straight forward. But when I started the car, I got two failure alarms ~ Fog light left and fog light right failure alarm.

I half expected it, as one of the installation step had me unpin contact X14261/pin 37 and X14260/pin 3 (which is the connection to the left and right fog light connection respectively from the Footwell module), and had nothing connected back into them. Thus the Footwell module detected open circuit and thus the alarm.

Putting the pin back removed the alarm.

With the alarm on, I tested the cornering light function but it did not work.

Therefore I would like to seek help here. Whether does anyone has access to any TSB (service bulletins) that talks about this Cornering Light function?

Perhaps the TSB will shed some light on how I can solve this problem. Note that the EBA stated that no programming required.

Appreciate it!

On the same note. Does anyone know how I can obtain access to ASAP (BMW's Aftersales Assistance Portal) to pose this problem that I am having?

Thanks again!

Did you manage to resolve the problem at that time ? I want to buy a cornering foglight set and I want to know if I can make it work.
Does anybody else put cornering ? Thanks

[dav_lph]

Yes, I managed to make it to work with lots of rewiring and connecting diodes to allow the Footwell Module into detecting the foglight is functioning.

Basically the retrofit kit's wiring harness is faulty. And rewiring is a must.

If yours is a E92, changing your head-lamp to a Adaptive Xenon (which does come with cornering light function) would be a better solution. But I know it will cost more.

Am I happy with the cornering light? Yes and no.

Yes, because it does provide the illumination during cornering. There is definitely the additional safety function acquired.

No, because there is no way to switch it off. It will function at speeds below 40kpm when light switch is in Auto or in Headlamp position.

No, because the cornering light does not fade off. It switches off abruptly when steering is straightened and not slow fade off. - I am thinking of wiring up a Capacitor to create the fading function...but have not got around to doing it yet.

I have a german version E90 from 2005, I cannot afford to put cornering xenon headlights, because it is a lot work and adding some modules. I preffer "the cheap" and easiest way.
Can you tell me what is it that Footwell Module ?
Did you have before simple foglights or no ? I have normal foglights.

[dav_lph]

The footwell module (FM) is the brain behind all the lights (interior lighting, exterior lighting, foglight, turn signal etc) and is located at the footwell.

This retrofit kit comes with a little module which will interface with this FM to read the car's steering angle and also when headlamp is on, and then turns on the foglight during cornering.

I also have the original foglight but you will notice that even when you turn it on, you do not get much light at the corner. This retrofit kit comes with two new foglight which replaces the existing units, and it is made such that it shines much more to the sides.

Note that to install the new foglight, a small part of the bumper around the existing foglight needs to be trimmed off.

HI dav_lph,
I know its an old theme,can you please send me some actual pics or if you can make a video ,how does it work - i want to isntall the retrofit into E46 and I want to see how actually works,cause i didn't manage to find any videos of that

[dav_lph]

Hi gqbriel,

Sure. Let me get back from my business trip and get a video for you over this weekend.

But do note that the Cornering Light module reads the "K-CAN" communication line to detect the steering angle and "light-on" signal to function. Therefore it will tap onto this signal from the Footwell Module (FRM). So I am not sure whether will it work on a E46 (does E46 communicates using K-CAN?).


Cheers,
David

Hi dav_lph

my name is Ben, I´m from Germany. I´ve bought this retrofit kit too, for my ´06 E90. I have the same problem with the lights... What do I have to change with the wiring to get it running?

PS: Sorry for bringing this "old" Topic back on top!

Greetings Ben

Hi dilated99,

It is very unfortunately that BMW actually sells something that is defective.

Anyway, there are two things that needs to be done to get the system to work.

1. See the first attachment below. I've marked up the terminal numbers that were on my wiring harness. See whether is it the same for yours. If it is, then what needs to be done in this step is to use a wire and connect from the wire on A8, pin 1 to A9, pin 14.

This provides power to the Universal Interface Module. And if you have completed your wiring according to the Installation Instructions, the cornering light will now function.

2. But you will now notice the car will give out Foglight Error. This is expected since the wire from FRM X14260, pin 3 and X14261, pin 37 is now wired to A1 instead, the FRM sees the output as an open circuit and thus shoots out the error.

The way to solve this is to parallel wire the foglight wire to A1 and also to the FRM. See page 2 of the first attachment.

I advise putting a diode on all these wires to prevent current back flow. See attachment below for the diode I used as a reference.

Diode.pdf

One more thing I noticed. If the steering is turned left or right when the engine is started, foglight error will pop up. All you need to do is to straighten the steering and restart the engine. Error will go away.

Let me know how it goes.

David

Hi David,

My Universal Interface Module, didn´t got power too.

I´ve taken the power from A8, PIN 1 (how you described it above) but I connected it straight with A8, PIN 6.

Now the Module is working.

Then I completed the wiring, like it´s described at the Installation Instructions from BMW.

It works, so I didn´t needed your 2. Step with the parallel foglight wire and the diodes.

But there are 2 "Problems"

I will always get an Foglight Error. (Maybe I have to deactivate the Foglights by coding!?) Cause now I can activate them over the cornering light modul.

My Cornering lights are going on, when I have my steering wheel in a 90 degrees angle...
I think they should only glow when the steering wheel is on the left or right end.

Hope you understand everything I wrote ;-)

Greetings from Germany.

Hi Ben,

Good news that the Cornering Light is now functioning.

With regards to your problem.

1. Foglight error always on.
Because we removed the foglight wire that connects from the FRM to the foglight and connect it to the Cornering Light Module, the FRM nows see an error. One way to solve this is to parallel wire the foglight wires to the Cornering Light Module and also the FRM. But to protect the Cornering Light Module and FRM, I propose putting a Diode to prevent current back-flow. I hope I am making sense.

You could try deactivating the foglight via coding but I am not sure whether would that allow you to turn on foglight manually after the coding.

2. Cornering light will turn on as you describe when the steering is turned 90 degress left or right. This is correct and normal operating condition, because you want to be able to see the sides when turning and usually the angle is around 90 degrees. Note that once the car travels above 40km/h, cornering light will automatically switch off.

Greetings from Singapore,
David

Hello David,

with the Foglight error and the wiring, that makes sense to me

My friend and I we have deactivated the foglight by coding. Because now with the Cornering Light Modul the Foglights are getting their "power" from this Modul... It´s all working perfect. Cornering Lights and Foglights!

So I didn´t needed the parallel wiring

to 2.

I understood how and when the Cornering light will go on and off... And its okay if i turn left or right into a street or something like that...
But its annoying sometimes, for example.... if i have to get slower because there are some cars who are parking next to my side of the street, and i have to pass by, the lights are going on/off/on/off ..
but thats cornering light.. ;-)

Regards

Ben

Hi David,
Been a while ,now with E90 330i what do I need for cornering lights.

I have FRMII module but no dynamic xenons only xenons and halogens ofc

Thanks in advance
