Thanks for your answer, but there is a control unit (modul ?) like that in interior, no ?? http://cgi.ebay.com/ebaymotors/BMW-A...Q5fAccessories

The AHL control unit is for adaptive headlights. And then there is the ALC motor/actuator on each headlights. The AHL I believe is located somwhere in the interior, maybe glovebox but depending on your years from 03/2005 it is integrated into the light module. To add to confusion, AHL and ALC are used by BMW interchangably. And the parts diagram have similiar name.

Also, link below has alot of info on adaptive and hopefully might find something there:

And here is the updated diagram for 03/2005 & after:

Hello

Thanks for your answer and these documents : very interesting !

I think that the best for me is to find adaptative headlights to code my light modul. I hope all will be good after.

Has anyone done this conversion (pre-LCI Bixenon AHL to LCI Bixenon AHL) and coded it themselves using NCS? What needs modifying and in what modules?

My car is build date 12/06 so has the later LCM, and the AHL modules on the headlights end in part number 312.

All the wiring is sorted, including the 2 wires from the back of the car to the LCM and swapping the 2 wires already on the LCM plug.

Thanks.

 

I know it has been said before but I tried searching for the answer can't seem to find it.. I have pre-LCI bi-xenon and adaptive they use d1s bulbs I just bought LCI bi-xenon lights with adaptive ... my car production date 02/06 do I need a new light control module or can I use the xenon parts from my pre-LCI? Thanks

 

Edit: I found the answer on page 9 thanks rootkit

 

krazi any update?

 

Hey guys ...

Could you please advise if this conversion is for Pre LCI Helogen to LCI Xenon conversion or Pre LCI Xenon to LCI Xenon? OR there is no difference?

Cheers!

 

to the forum!

This conversion is for pre-LCI Xenon -> LCI Xenon ... and there's a HUGE difference if you do cross conversion ... trust me I did pre-LCI Halogen -> all the way -> LCI Xenon and rather more complicated ... not so fun
