Adaptive lights

[Lanister]

Do you guys know if you can enable/disable adaptive lights behavior in LCM? or perhaps another module? Ever since I got my LCM 4.0, my head lights aren't moving when I turn so I figure it's just disabled since the car it came from probably didn't have this option. I just wanted to see if my assumption is valid.

If the LCM you have didn't come from a car with adaptive headlights, then it's not going to work because there's circuitry inside of the LCM that makes the Adaptive portion work.

Do you have the part number? It will tell if this is the case.

I'm not sure if the halogen-equipped facelift coupes/verts had adaptive functionality or not. I know the Xenon ones did.

Didn't think there were halogen equipped facelift coupes...weren't they all 2.5 inch bi-xenons?

There existed halogen facelifted cars. It was kinda weird but they do exist, they had projectors but were non-xenon.

Sorry to hear that but I'm betting it's because it wasn't from a facelift coupe. That was why I questioned whether your lights were still swiveling last week. Like I said........I'm beginning to think it might just be easier to go with a new one.

It look like this must be the one you have......

Don't mean to thread jack but on the subject of the adaptive lights, has anyone had theirs stop swiveling from parts failure yet?

This isn't true; it's not the same as autoleveling LCMs. On cars with adaptive headlights, the vertical and horizontal adjustment is handled by separate modules which the LCM communicates with over the K-bus (or maybe the CAN bus). Even a halogen LCM would work fine in this case (in fact, the adaptive LCMs are electrically identical to halogen LCMs, save for the switch with the green LED). If it's not working, it wasn't coded properly.

If the LCM was coded before you got it, I'm guessing the person who coded it did not add $524 to the VO/FA

This isn't true. The adaptive functionality is handled by a different module, which the LCM communicates with over the K-bus. Even a halogen LCM would work fine in this case (in fact, the adaptive LCMs are electrically identical to halogen LCMs, save for the switch with the green LED). If it's not working, it wasn't coded properly.

Yeah I learned this info this past weekend. What I said is stuff I've read online in other places numerous times and did not realize it was false info. Thanks for the correction.

Yeah it's a little hard to keep track of what is compatible with what. I should make a table... though I don't know how I'd organize that.

In general:

You need an LCM with the same SW number as your car or newer. There are some minor exceptions to this rule where an older unit is allowed
Non-adaptive HID LCMs can be used in any car as long as you have the right SW# for your car.
Halogen and adaptive LCMs are interchangeable. They can also be used to power non-adaptive xenons if you're willing to sacrifice autoleveling
LED tails and facelift sedan tails require an LCM that is SW 3.1 or newer
SW 3.1 - 3.2 LCMs from coupes/verts/tourings are not compatible with facelift sedan taillights (inner trunk lights won't work)

Thanks for the info Terra. Looks like I was wrong in assuming there was a separate LCM for Adaptive lights.

[Lanister]

Awesome and very helpful info. Thanks terraphantm!

In doing my research, I found a site that shows application guide for my sw 4.0 LCM (Part# BMW 6 965 390), and it happily includes the 330Ci along with 330i and many other e46 models. So it is a matter of coding the LCM to enable adaptive lights. Sounds like a worth-while challenge. :)
