Do i need to change any wiring?

Hi Guys

My car has self leveling, auto halogen headlights. I am fitting OEM Bixenons that my car came with if you ordered the option.

Does anyone know if the wiring is a straight plug/play between the Halogen/Xenon ?

The Xenons I ordered are complete, all the bulbs, ballast and so on (All OEM BMW stuff)

Thanks!

glad you finally got yourself a set. no change in wiring should be needed.

The bi-xenon wiring is different than the halogen one. You will need to either:

Mod the existing wiring to operate the bi-xenons & get rid of the bulb failure warning. Bi-xenons have a 3rd plug that triggers the flap when you turn on the high beams.

or

run new wires from the headlights up to the LCM. I haven't seen a bi-xenon wiring loom for sale so you will probably have to make your own. Then you will have to find out which pins on the LCM correspond to the bi- feature. After you finish with the wiring, you must take your car to the dealer to recode the LCM for bi-xenons.

The only plug and play thing are the headlight screws, low/high beam plugs and autoleveling plugs

yea, so in essence, it's the same. he doesn't need to change anything unless he wants to make the bixenon function work.

****, well yes I want to use the bixenon function... So I need a wiring harness, oh god! That will be impossible to find or work out how to get it working. Will I need to recode the LCM to get Xenon low beam working only without warnings?

Ok, found a few DIY guides, all very complex but maybe a smart electrical guru can do it here locally.

Seems its a straight fit for a low beam xenon only. And if they flicker, ill get my LCM coded to BiXenon and do the retrofit/DIY project

If i buy a local LCM for biXenon can I just swap it over? I heard there are milage tamper issues with swapping over LCM's?
