I'm looking into this myself but I've noticed that I have FRM1 module which obviously isn't enough for this kind of modification... Could someone please tell me if upgrading to FRM2 will be enough? I know, FRM3 would be the best choice, but it's harder to get used one...

FRM2 would be fine (FRM3 optimum as you stated) I have LED tails on my 09' E92 with FRM2.

You will have to code (or know someone that can do for you) out the rear Cold/Warm Bulb checks and the Error Reporting.

After that, all is fine, no flickering or hyperflash...

A DCAN cable is on it's way from England and I've already checked all manuals and videos of doing the coding, so I was thinking of doing it myself since each step is explained to the details.

Thanks for the info! I'll post some pics when I get it done.

sorry for the bump, E90Sexion, can you confirm that you set brake force display (BFD) to nicht_activ also?

Thanks for the post btw, will update if I have success with coding the LCI retrofit

yea I remember doing that, BFD
whatever says in the early post that's all you need

[mrajkovic]

I can confirm that I've successfully managed to get LCI taillights working on my 2006 e90 without FRM upgrade.

I wanted to disable bulb checking with the ncs codes provided in #1 post but my FRM module didn't have the exact values, so I had to disable each bulb individually:

KALTUEBERWACHUNG_BLK_H_L
nicht_aktiv
KALTUEBERWACHUNG_BLK_H_R
nicht_aktiv
KALTUEBERW_RL_BL_2_L
nicht_aktiv
KALTUEBERW_RL_BL_2_R
nicht_aktiv
WARMUEBERWACHUNG_BLK_H_L
nicht_aktiv
WARMUEBERWACHUNG_BLK_H_R
nicht_aktiv
WARMUEBERW_RL_BL_2_L
nicht_aktiv
WARMUEBERW_RL_BL_2_R
nicht_aktiv

This is it, fixes bulb checking (flashing) on the car startup and normalizes blinker speed...

(tested on FRM1 2006 build)

I had to add a little more on my FRM E92 late 2006 build to get everything code free


KALTUEBERWACHUNG_BLK_H_L
nicht_aktiv
KALTUEBERWACHUNG_BLK_H_R
nicht_aktiv
KALTUEBERW_RL_BL_2_L
nicht_aktiv
KALTUEBERW_RL_BL_2_R

KALTUEBERWACHUNG_BL_L
nicht_aktiv
KALTUEBERWACHUNG_BL_R
nicht_aktiv
KALTUEBERWACHUNG_BFD_L
nicht_aktiv
KALTUEBERWACHUNG_BFD_R
nicht_aktiv
WARMUEBERWACHUNG_BFD_L
nicht_aktiv
WARMUEBERWACHUNG_BFD_R
nicht_aktiv
WARMUEBERWACHUNG_BL_L

WARMUEBERWACHUNG_BLK_H_R

WARMUEBERW_RL_BL_2_L

Finally coded my LCI tails, just disabled ALL cold/warm bulb checks. I would know if my bulb goes out anyways.

[eezeekial]

I have one weird thing going on. I have a right turn signal malfunction message but everything seems to be fine with the lights. They are all blinking at the right speed. I double checked all the code and all the L & R's I have posted above match. Anyone seen this before?

Maybe this is common sense but I screwed it up. So just in case you seem to have your right tail working perfectly but your left reverse light does not work then you need to mirror this pic for the connector on the left side everything is opposite.

However, when the parking/headlights are on the LCI bars light up as well as the outer brake light (as if i had the brake pressed). Is this common until I have properly coded my car?

Hi, can anyone help I'm having the same problem as the above?

Did you do coding?
What is the date of your car etc.

Hi, cheers for the reply... Yeah it's a 2007 and I've bought the wiring harness from BM and fitted it in the boot which all works fine but the outer lights are the problem, they are lighting up the LED lines as normal but then the right brake light is illuminated also, the other brake light wont light up even when you press the pedal but does when lights are turned fully off as the guy in the old post explains??

No not had coding done but I was thinking that was just to remove the bulb failure light on dash?

Cheers

I have the same problem, should I upgrade the FRM? it's 2006 E90.

[mattisere]

Yeah, think this post needs some love! About to do my conversion and would really REALLY appreciate some help coding as I have NO IDEA what i'm doing!?

[maxq]

mrajkovic, can you please confirm that your tails are still working? My worry is if the FRM1 does not provide adequate voltage/current to the tail lights, it may either harm the lights or the FRM itself. Did you experience any failures over time?

Also, tips from makkan00 and NiVeDh made the trunk light rewiring a piece of cake. Thank you!!!

I only have to do coding now but just waiting on confirmation on long-term use and effects of using FRM1 with LCI tails. Can anyone provide insight on the matter?

Wiring for my 12-2007 build E90 M3 was different.

I tried to re-wire as shown earlier in this thread and that didn't work right for me, the wrong lights were lighting up. (rear fog instead of reverse, reverse instead of park). So the wiring must not be the same for all cars.

Busted out my tester, and this is what made everything work correctly for me:


Coding after that was easy and error free.
