    Halogen to Xenon in Sedan. What's needed?

    So, I've been presented with an opportunity to buy Xenon headlights for CHEAP!

    I'm pretty sure it's headlights and bulbs only however along with AE's.

    I know I'll need ballasts, but anything else? Harnesses? Coding the car for Xenons?

    This will help make my decision.

    From my understanding, you can program the car for the Xenon's. There's some info out there on it.

    Just want to be 100% sure what i'm getting myself into.

    There is going to need some coding involved because of the Bi-Xenon actuators.

    As far as to what detail, I'm not too sure.

    On the E82 I know you have to change your pin out location that connects to the headlight for proper function

    Or you can try this retrofit from e46F.

    and it depends on if you are getting xenons, or bi-xenons. are they OEM or DEPO? xenons would need error cancelling ballasts, but bi-xenons (oem) should be able to be programmed.

    Yup, you can. You have 3 options in NCS - Halo, Xe, Bi-Xe. Make sure you're swapping in M3 AL projector housings while you're in there to avoid burnt bowls

    I think you need the leveling sensors on the control arm too?

    Couple corrections: Adding option code $522 will always add bixenons to a 2002+ E46. "regular" xenons were not offered at all then, thus the option code superseded it. You can recode the highbeams to the Euro settings so that the car opens both the shutters and the halogen highs at the same time -- effectively making it single xenon if you don't have shutters wired up

    Any AL projectors will do. Plenty of sedans and non-M coupes got them. I personally got the AL housings for my non-M E46 from an 02 325i.

    Either can be taken care of with coding. I wouldn't bother with error cancelling ballasts at all -- they're hit or miss.

    Autolevelling is a major PITA to retrofit. Requires you to run a couple harnesses -- not worth the effort for the minimal gain

    Retrofitted mine in with no issues. Went from 2000 halogens to 2002+ Bi-xenons with minimal effort. Only challenge was wiring the shutter solenoids. I later found out that pins 2 and 36 control the shutters. Just had to run the length of wire to the actual shutters to earn the stripes.

    From a GS3, this was sent.
