DIY LCI-xenon retrofit to a preLCI halogen - error free

Heya guys,
I managed to retrofit my 2007 320d which came with halogen stock lights to a 2010 LCI non-adaptive xenon.

I will start off with - this is EXTREMELY easy if you are semi-tech savy. I did everything on my wire hareness - NOT INSIDE THE HEADLIGHT.

Since I don't have a lot of time for the complete write up i will do a quick summery for you and will go into detail later this week.

Step 1 pop out your connector.

Step 2 - preLCI halogen has teh ground on Pin 4, LCI xenon needs a ground on Pin 2 so run off to your dealer and buy several pins(realoem numbers later this week) and get some 10-12g cable (I soldered mine but you can use wire taps). So connect Pin 4 to Pin 2 and voila you have low beam xenon with a TON of errors

Step 3 - Pin 6 is your full beam but if you get lights from a 2011 model that's your daytime running light and full beam is only in the bixenon shutter so you need to either move Pin 6 to Pin 5 or tap them together - option 1 gives you full beam xenon only, option 2 you get full beam xenon and halogen.

Step 4 (optional) - if you want those 3 corner leds Tap pin 1 to Pin 7

Step 5 - Coding

Disable auto leveling (i will retrofit the self-level sensors later on)

Add $522 in your FRM(in order to have error free xenon you need at least FRM2 or NFRM)

For full beam functionality Option 1

For full beam functionality Option 2

Since I went with full beam on both bulbs I had an error after coding in the xenon so I disabled the hot and cold bulb checks.

Since I had FRM2 I didn't have the LED blinker option and I was getting an error for the blinkers - disable the check and you are good to go.

Photos and indepth guide later on, for now check it on my car (it is really dirty but hell I washed and detailed it on the next day)

DISCLAIMER: this DIY assumes you know your way around coding and some electrical skills, if you have those two skills you are golden.
