Hi Jat,
I started researching and collect parts a few weeks ago after realising that my headlights looked quite pathetic in the dark, I even put installed Philips Xtreme vision bulbs but it didn't help much.
Anyway I found some info from this thread
http://www.e90post.com/forums/showthread.php?t=887687 but I found out that the part number for the wiring harness was out of date.
To date I obtained:
1. Non-adaptive pre-LCI xenons from eBay.
2. 10w angel eye LED bulbs, eBay.
3. 2 level sensors, eBay.
4. Wiring Kit (the box can be seen in the photos!)
5. Most of the bits from
this page on realoem excluding the sensors and a couple nuts/bolts as I already had them.
6. FRM2 footwell module (already in the car)
7. Light switch, check on
this page for the correct one. In my case I needed part 61316932798. This was found on eBay.
I've still not done everything although I only started fitting the parts last weekend. The wires are as installed as far as the footwell module but I haven't actually plugged them in yet.
I then need to code the car (finally got NCSExpert working properly yesterday
)
I also need a few hours free (when the wife isn't looking) to remove the bumper and install the new lights.
Hopefully I'll be finished by the end of this weekend!
I presume LCI lights can be fitted but I don't know if/what the changes may be. I wanted as close to OEM as possible.
