[BMW335l]

I'm thinking about changing my pre lci tail lights to either lci or lci blackline. Which one do you guys prefer?

And is the procedure exactly the same for blackline as with the regular LCI?

Yup

The taillights are a direct fit in place of the pre-LCI ones but need a 6-pin connector instead of the 8-pin connector.

The old connector had 3-pins for the 3 brake light bulbs while the new one only needs one. While some people have opted to solder the 3 brake light wires together and connect them using a single pin. I opted to only use one of the pins, specifically the inner brake light pin since that is the one used for the brake force display function. The other two pins remain in the old connector and is left dangling next to the new connector in case the installation needs to be reversed for whatever reason.

Parts List:

• Left Taillight: 63217420991
  
• Right Taillight: 63217420992
• 6-Pin Connectors (2x): 61132359993

Tools:

• 10mm Socket and Driver
• Pick tool or narrow flat-head screwdriver
• ENET Cable and coding software (E-Sys)
• Electrical tape
• Masking tape (optional)

Instructions:

1. Cover the area right below the taillight with masking tape because you risk scratching the bumper when pulling it out.
2. Open the trunk and open the two plastic covers covering the two 10mm nuts on the taillight and unscrew them.
3. Give the taillight a good tug and it will come out. The outer side is held in with a snap-in rubber ball thing so it needs a good tug.
4. Remove the 8-pin connector from the taillight. First unlock the connector by pulling on gray locking tab and then pull on the connector to remove it.
5. Put the old taillight aside.
6. Now open the small pin-locking plastic pieces on both sides of the connector locking the pins in place.
7. Remove all pins from the 8-pin connector except the two non-BFD brake light pins. To remove the pins just unlock them by pushing on them using a pick tool through the newly exposed area.
8. Remove the purple locking tab from the new 6-pin connector and correctly insert the pins into it according to the pinning guide. Don't forget to insert the purple locking tab again.
9. Now wrap the old 8-pin connector with the brake light pins with electrical tape so no water can get in there and corrode the pins.
10. Plug in the new connector into the new taillight and install the taillight. Make sure while installing the tallight that the rubber drip rail is not bent and is correctly sealed against the body of the car.
11. Repeat for the other side.
12. Code the car

LCI Left:
Pin 1 Gray / Pink = BFD/Brake Light
Pin 2 Black / White = Turn Signal
Pin 3 Brown = Ground (-)
Pin 4 Gray / Violet = LED Bar

Would the coding settings above be suitable for pre lci to gt style upgraded lights or would that coding package not work?

[TrboMike]

I assume the GTStyle is all LED. You'd have to code the car to tell it which are LED and leave alone those that are not, the above coding assumes all is LED except for the reverse lights. Other than that the only thing you might not want to do it the mapping to the 13.7 voltage. You might want to fork with the voltages to make sure you get the blink rate/brightness you want out of the LEDs. But thats just playing with it to get it the way you want.

LCI everything is LED except backup lights. So you would need to set TURN LED CONV to yes, FOG LED CONV yes, INNER TAIL to yes, etc.... everything except reverse lights, unless you choose to replace your new LCIs with LED backups at the same time. Then those too.

Sorry to revive an old thread, but you say i just need to set them to active, so no need for expert mode ?

Last time I was in bimmercode all the LED taillight settings were put in normal mode so no need to hunt in expert mode.

Okay, thank you 🙏🏼

Hi everyone,

I was wondering if anyone has had similar issues to what I am having. I have a 2017 m240i and am converting to LCI tail lights. I followed the instructions and coding exactly, used Bimmer code, but only my right blinker and brake light work. Any ideas on what to do? Thanks in advance.

did you buy the lights new? Do you get errors on the display? Have you read out the errors with BimmerLink?

What does WORK mean? They dont light up at all? Then you have a physical wiring problem. Fixing the coding will only stop the LEDs from blinking at startup and random times when the computers "check" for a burnt out non-LED bulb.
