▀▄ eas | DIY: LCI Tail Light Upgrade for F80 M3

The M3 has been on the market for a little over a year and already we're seeing the LCI taillights on the MY16 models.

Unlike it's E90 predecessor which included changes to the trunk, the F80 LCI Taillight upgrade is a simple taillight swap that can be accomplished by the DIY type.



The release of the 2016 LCI (Life Cycle Impulse) introduced some minor improvements to the vehicle. On the exterior side, most noticeably with the taillights. This DIY will give a quick overview for those to update their lighting to update the rear of their 2015 M3 Sedan to appear like the 2016 models.



An LCI Upgrade from EAS consists of Inner/Outer taillamps, trunk lamps (4 total) and Plug and Play (PnP) harnesses.



History

EAS has been performing R&D on taillight retrofits for a number of years, leading back to the E46 M3 models. We were at the forefront of the E92 taillight swap back in early 2010, with open Q&A sessions to fully explain the steps and show a bit behind the scenes on R&D:

Harness repinning


In the next series of steps, we will be repinning the Outer Taillight connectors. This is a basic procedure and only requires a few steps, and completely reversible.

Overview of steps being performed - LEFT TAILLIGHT
Remove Black/Yellow from Position #1 and insert into Position #2
Remove Black/White Wire from Position #2 and insert into position #1
Remove Grey/Violet wire from Position #5 and insert into position #4
ScotchLock clamped onto Black/White wire (POS1)

14. Start with LEFT Outer Taillight connector.



15. Remove the purple retaining clip by sliding sideways. This will allow the pins to be properly removed.



16. Remove the weatherproof plug in plug position #4 with a pick tool and set aside. We will be replacing this later.



17. Wire positions #1 (Black/Yellow) and #2 (Black/White) need to be swapped. Remove Black/Yellow wire from connector on position #1. This is a (2) step procedure with your pick tool on the retaining barb on the connector, while carefully pulling outward. Repeat same steps for Black/White wire on position #2.



18. Photo of completed wire swap. Note Black/White wire is now in position #1 and Black/Yellow wire is in now in position #2. We've also removed Grey/Violet wire from position #5 and relocated to position #4.



19. Reinsert weatherproof plug in plug position #5.



20. Clamp supplied ScotchLock onto Black/White wire (POS1).





21. Move onto RIGHT side taillight and repeat steps, noting colors are slightly different than left taillight.

Overview of steps being performed - RIGHT TAILLIGHT
Remove Black/Blue from Position #1 and insert into Position #2
Remove Black/Grey Wire from Position #2 and insert into position #1
Remove Grey/Yellow wire from Position #5 and insert into position #4
ScotchLock clamped onto Black/Grey wire (POS1)



22. Reinstall LCI inner Trunk Lamps, using steps outlined above. Starting from LEFT LCI trunk taillight, insert supplied harness into connector, paying attention to RIGHT and LEFT harness, as they are slightly different. LEFT harness will have a longer BLUE wire hanging from it.





23. Repeat steps for RIGHT side, noting that RIGHT harness has longer ORANGE wire hanging.



24. Route BLUE wire down trunk bracket.



25. Route BLUE wire through trunk liner, near taillight area.



26. Route BLUE wire through locating pin hole behind taillight.



27. Strip BLUE wire and crimp supplied connector onto wire end and connect to Black/White wire on position #1.



28. Repeat steps on RIGHT side, plugging into Black/Grey wire.



29. Reinstall trunk Liner. Replace LEFT/RIGHT trunk bracket trim pieces, keeping wires neatly tucked underneath.



30. Reinstall Outer Taillights. Close trunk a few times to ensure enough slack is present in wiring and does not catch up on trunk tension springs.



31. Installation complete. Stand back and admire your handywork.

Coding

Coding is necessary in order to keep errors from appearing when new taillights are installed.

REM Module
REM -> BFD_L_IS_LED: aktiv / Werte=01
REM -> BFD_R_IS_LED: aktiv / Werte=01

REM -> FRA_H_L_KALTUEBERWACHUNG: nicht_aktiv / Werte=00
REM -> FRA_H_L_WARMUEBERWACHUNG: nicht_aktiv / Werte=00
REM -> FRA_H_R_KALTUEBERWACHUNG: nicht_aktiv / Werte=00
REM -> FRA_H_R_WARMUEBERWACHUNG: nicht_aktiv / Werte=00
REM -> FRA_H_R_IS_LED: aktiv / Werte=01
REM -> FRA_H_L_IS_LED: aktiv / Werte=01

REM -> NSL_L_KALTUEBERWACHUNG: nicht_aktiv / Werte=00
REM -> NSL_R_KALTUEBERWACHUNG: nicht_aktiv / Werte=00
REM -> NSL_L_WARMUEBERWACHUNG: nicht_aktiv / Werte=00
REM -> NSL_R_WARMUEBERWACHUNG: nicht_aktiv / Werte=00

REM -> RFS_R_KALTUEBERWACHUNG: nicht_aktiv / Werte=00
REM -> RFS_L_KALTUEBERWACHUNG: nicht_aktiv / Werte=00
REM -> RFS_R_WARMUEBERWACHUNG: nicht_aktiv / Werte=00
REM -> RFS_L_WARMUEBERWACHUNG: nicht_aktiv / Werte=00

REM -> RFS_L_IS_LED: aktiv / Werte=01
REM -> RFS_R_IS_LED: aktiv / Werte=01

Install is complete. Please comment and [appreciate] if this guide helped you or if any of the steps need a bit more detailed explanation.

We are fully stocked with US kits, but we may consider importing EU versions if there's enough interest.

Great write up.

Have had my LCI taillights for a month now, and I finally have time to install them. Gonna be ordering the harness in the morning.

Now to find someone local that can code this in...

We've been doing retrofits on these and other areas of BMWs for over 10+ years, and have the experience/equipment necessary to do so.

No idea on other methods used, but wanted to make the info free/public.

Should have no problem finding someone in your area to code, or make a quick trip up this way and I'll handle it. We'll also be turning over notes to Autologic so independents have access to retrofit coding as well for those not in the local area.

Coding would need to be performed in your area by a local coder. The fields needed to change are listed in the DIY.
