Coding: Rear Light Bars Remapped For Turn Signals - Still Enabled for Tails

The thread about the Eyebrows remapped for turn signals over here - http://f30.bimmerpost.com/forums/sho....php?t=1264291 got me thinking...

Is it possible to remap an addition function for the Rear Light Bars to function as turn signals without removing the taillight function?

The answer...



YES!

Simply remap the following:

MAPPING_TAGFAHRL_H2_L_OUTPUT > sl_2_l
MAPPING_TAGFAHRL_H2_L_FUNCTION > werte 06
MAPPING_TAGFAHRL_H2_R_OUTPUT > sl_2_r
MAPPING_TAGFAHRL_H2_R_FUNCTION > werte 07
MAPPING_TAGFAHRL_H_L_OUTPUT > sl_l
MAPPING_TAGFAHRL_H_L_FUNCTION > werte 06
MAPPING_TAGFAHRL_H_R_OUTPUT > sl-r
MAPPING_TAGFAHRL_H_R_FUNCTION > werte 07

So in order for the light bars to be repurposed as turn signals (still function as taillights at night) - we're remapping the supposed DRL functions for the taillights to be used as turn signals instead.

This is a good find! Thanks for sharing!

Edit: worked like a charm!
The codes you mentioned are under REM. I was mistakenly looking for them under FEM_BODY.

I just noticed that when I have my left indicator turned on, there is a click coming from the back right of the car.

I don't have any such indicator clicking noise from the back right or left other than the regular indicator clicking when I have the right indicator turned on.
Any ideas what that could be?

code to turn off the blinker and just use the leds

I coded the led light bar to link with the turn signals but looks a little tacky with all 3 lights going off. Is there a way to turn off the regular turn signal so I can just use the lower led light bars as turn signals?

I'll look at it when I have time. But really you just have to turn off the mapping of the turn signals to the regular bulb.

In addition to werte 04 for DRL function, the output was off, since the rear DRL is not activated from the factory.

I'm getting an issue where the outer left bar blinks while the inner bars (closer to the middle of the trunk) in the left side don't blink when the car lights turn on. Otherwise when the headlights are off the function as expected. I've gone through and coded everything correctly so not sure what gives?

What values need to be modified to turn off the actual turn signal bulbs and use the lower bar leds as activated here?

It can be coded, and we can disable the yellow signals too.
Just disable blinken values
