My X5's bi-xenon bowls are toast basically and don't put out the best light in the world.

I got around this on low beam by putting LED headlight bulbs in the driving lights. So with them on I can actually see on low beam at least.

But since they cut off when I go to high beam my light output actually was cut in half when I flipped the high beams on.

I just coded this in ncsexpert

High beams on with bi-xenon (LCM)

PWM_FL_BIX - wert_01 (Changed)


Mine was set to wert_02. By changing it to wert_01 when I now turn on my highbeam lights my xenons go to the high position and then the high beam halogen lights kick in. Pardon the pun but its a night and day difference. I doubled my high beam light output.

Best coding mod Ive done to date. Well worth the effort.

Again I know it was covered in parting in other threads but this one was big enough to be worth its own spot.

This will save me having to buy the reman active xenon replacements for a bit now and at $600 each for the remans of these that's $1200 saved for a few minutes coding.
I'm currently trying to improve the light output on the Bi-Xenon Setup of our '06 X5 3.0. The light output of the Xenon as low beam light is extremely shitty - driving the car at night is far from being pleasant (I'm not talking about high beam mode).

So basically what you suggest is using the fog lights together with the xenon in it's low beam mode, right? Besides that, you are replacing the fog light bulbs with led bulbs to gather a better light output from the fog lights (which we hardly ever use).

I can turn the fog lights on manually and this would be OK for me, since I wouldn't need them to be on during the day. Still, coding the feature on would not be a big problem for me but I would try to go the manual way first and see how it works out for me.

If I got everything right, I would like to try this mod to hopefully improve driving by night. Just 2 questions:

- Which led bulbs / setup do you suggest? The link on your page is not valid anymore
- What does it take to install these led bulbs into the fog lights?

Thanks a lot in advance for your support!

The low beams are helped by the driving lights in the bumper after upgrading them to led headlight bulbs


The high beams are helped by coding the inner headlights (only works as flash to pass pulling the stalk when not coded) to stay on as high beams.

I updated the link on my site for the led bulbs.


As for whats required to install them. Remove the old bulbs and install the new bulbs. No mods needed.

You never needed error resistors to operate the LED with no errors on dash cluster?
Or did you just code off all hot and cold monitoring?

Resistors are a BAD idea with lamps like head and fog - you need to use such a low value resistor to simulate correct load that the power dissipation is nuts and can melt plastic bits near the resistors etc. - a 50W resistor is huge and gets VERY hot.

Not to mention the waste of power...

Just code off the hot and cold monitoring.

Maybe you know which of those is responsible for the front fog lights? My guess would be Front & Right Low beam light.

That doesn't look like the LCM settings for a E53. That looks like the one I have for my E46 when I look at BMW Scanner 1.4 LCM settings. Your E53 should look like this one with left and right fog lights clearly listed.

Well, this makes things much easier ^^. I just picked a picture from google assuming it would be the same for all models. Great, this will be easy, thanks a lot!!

So how do you guys code exactly?? Like what do you use and how do you hook it up? Never understood it really.
