F30/31 LED Turn Signals working

Finally found a nice set of LEDs which produce enough light:
http://goo.gl/aFPlrC (perhaps there are cheaper alternatives)

I had first installed more powerful CRE LEDs but they did not reflect anything and as a result were not bright enough when compared to the original bulbs :(

Yesterday evening I shot a short video, looks nice doesn't it ? :)



Note that self-diagnosis regularly injects a current to check the presence of light bulbs. While not sufficient for a light bulb to lit, this will make the LED flicker at start-up and every 4 minutes when the engine is on. Self-diagnosis must be turned off through coding :

FRONT
FEM_BODY 3061 FRA_V_L_KALTUEBERWACHUNG -> nicht_aktiv
FEM_BODY 3061 FRA_V_L_WARMUEBERWACHUNG -> nicht_aktiv
FEM_BODY 3061 FRA_V_L_IS_LED -> aktiv
FEM_BODY 3061 FRA_V_R_KALTUEBERWACHUNG -> nicht_aktiv
FEM_BODY 3061 FRA_V_R_WARMUEBERWACHUNG -> nicht_aktiv
FEM_BODY 3061 FRA_V_R_IS_LED -> aktiv

REAR
FEM_BODY 3061 FRA_H_L_KALTUEBERWACHUNG -> nicht_aktiv
FEM_BODY 3061 FRA_H_L_WARMUEBERWACHUNG -> nicht_aktiv
FEM_BODY 3061 FRA_H_L_IS_LED aktiv ->
FEM_BODY 3061 FRA_H_R_KALTUEBERWACHUNG -> nicht_aktiv
FEM_BODY 3061 FRA_H_R_WARMUEBERWACHUNG -> nicht_aktiv
FEM_BODY 3061 FRA_H_R_IS_LED -> aktiv

Hi benoa
I installed the spektrum led for rear turn signal, and when I start the engine, like u said, the bulb flicker,
But when I trying to find the right rear code, I couldn't find it, only the front codes.
I m assuming there are different code from sedan to wagon.
I replaced the bulbs back to OEM, but I really want that led turn signal,
Do u know how to get it fix?

Finally, I finish my installation.
I was doing research about the code and i found your blog, I see that you corrected your post, it should be "REM" root for the rear not the "FEM_BODY".

And I also notice that there is one more problem, when I turn the power on and open the trunk, I heard a very very tiny noise "Bi----------", sounds like computer POST, I think it is BMW system's POST, but i don't see any error code on dashboard. Got any idea?

Would happen to know the coding for this for the reverse lights? I installed LED's there do and I have the flicker problem which I've been told is very noticable.

No clue, sorry.

Would also be interested to know. I asked a similar question about the break lights but no answer either

Have you had any problems with your bulbs from Extremebrightleds.com? I picked-up the same set from them a year ago, and one of the diodes on the bulb burnt out after 35 day. I tried contacting them through e-bay and their website but I was pretty much ignored. I also noticed the bulbs would dim and turn a shade of orange pastel when on low-beam if the side maker lights weren't coded out.
