Retrofitting adaptive Xenon To adaptive full LED

[larry_bml]

So, yesterday afternoon I found another pair of Adaptive Led headlights, I took them and installed. It took almost one hour , to uninstall bumper, old broken headlights and install new ones, as wiring was already done. They got coded for the first try and they are lighting up as they should. Everything works , except I have an error with vertical aim, but strange it goes off after driving away. I don't understand why. Tried to initialize level sensors with ISTA +, ICM said that sensors were correctly and successfully initialized, but at next scanning there is again error. I did some coding in FEM_BODY, LWR_ENABLE - aktiv, and now error goes away after a few seconds after starting the car. I tried to test light distribution but they are not aligned as they should and I couldn't be sure if they are working or not, but HBA stays ON on high speeds even behind another car, and the driver said that my lights were not disturbing him (it was a friend of mine ). So I think light distribution is working too. The only thing that is not working is auto leveling, cornering is working. Maybe a little more coding needed. I will ask some friends.

Today my headlights had arrived, I will start install process in the afternoon.

I will come with updates tomorrow. I pray for everithing to work

Where did u buy the headlights from?

[larry_bml]

Ebay

Hello, I just installed my Adaptive Led on my F30 2012. Everything is working as it should , only one minor problem. From time to time I have error for vertical AIM control, if I start Rheingold and do an initialization of TMS sensors, error disappears for 1-2 days, and after that it came back. For the firs 1-2 days it is shown when I start engine, but after driving a little it disappears by itself, but after 1-2 days it no longer disappear anymore until I don't do TMS initialization again. Can anyone give me an idea on how to fix this, please?

[Dumpspec]

is the wire harness plug and play?

[larry_bml]

Yes

Where is the best place to buy the headlights from? I've looked a bit on eBay but not much comes up and most don't have bulbs or modules.

If you allready had adaptive xenon lights, you need to do more then just put in the wiring harness and coding, you need to change 2 wires from each headlight and 4 in the front electronic module

can you please explain which pins are need to change in headlight and FEM?
my car (F32 10/2016) has xenon without adaptive headlight before and i want to change the wires up to adaptive LED headlights.

Here are my actual wire colours at the right headlight.

PIN Colour Section Function
1 Blue 0,75mm² 49VR (Turn signal right)
2 Brown 2,5mm² Earth
3 Yellow/Blue 2,5mm² ?
4 Brown 0,75mm² ?
5 Grey/Yellow 0,75mm² ?
6 Green/Black 0,35mm² ?
7 Brown 2,5mm² Earth
8 White/Yellow 0,35mm² LIM_LIN_1

I see for the moment there are no CAN2-Wires at 9 and 10. Only 9 and 10 need to be added or 11 and 12 too?

[M4_MLT]

I am looking to do this too , I asked my BMW Dealer and he says that BMW doesnt offer them service for Retro Fit , is it true ?

Hi guys,

i am so frustraded with my retrofit of full adaptive led headlights at my BMW f32 from 10/2016.
The car has before xenon headlight (non adaptive).

So i bought two adaptive led headlights and check the wiring in ISTA.
Change one 12V PIN3 and added 4 wires at the headlight plugs (9+10 K-CAN2 for TMS Modules and 11+12 K-CAN2 for LHM2 Modules).

After this i edit the VO and delete 522 for xenon and add 552 for adaptive LED.
Code the FEM_BODY with the new vo and now nothing works.
I check wiring again in ISTA and measure the voltage at the headlight plugs. All is ok.
Now again go to ESYS and read all ECUs from the car, now there are two LHM ECUs, i select the right cafd and code both LHMs. After this low beam and high beam working perfect.
But the two TMS are not detected now. Ok check the wiring again and read fault codes.

There are these fault codes in ISTA:
"0xD90D2F Treiber-Modul Scheinwerfer (TMS) links: Fehlender LIN-Slave" (lin slave to TMS modul left is missing)
"0xD90D31 Treiber-Modul Scheinwerfer (TMS) rechts: Falsche Variante verbaut" (wrong variant of tms module are detected)
"0xD90D32 Treiber-Modul Scheinwerfer (TMS) rechts: Fehlender LIN-Slave" (lin slave to TMS modul right is missing)
"0xD90D37 Innenlichteinheit (ILE): Falsche Variante verbaut"
"0xD91DE0 CAN-Botschaft, Status Licht Außen Frontelektronik_1 Links (ST_LP_EX_FE_1_LH): Timeout"
"0xD91DE6 CAN-Botschaft, Status Licht Außen Frontelektronik_1 Rechts (ST_LP_EX_FE_1_RH): Timeout"

I try to code FEM_BODY "TMS_ID_CHECK" to not_active. But fault is the same.
Now i try to go to ISTA -> service functions -> ABL LED-Headlights and the result is both TMS modules are unreachable for ISTA.
so i unplug both led headlights and recode 522 for xenon, plug the xenon headlights to car and all is working, also the LIN Bus to both TMS modules.

So there is no fault with lin bus...

Recode 552 for adaptive led headlights and plug the adaptive led headlights back again.

I checked all, so i bought two brandnew TMS Modules for these car.
And the result is, the same fault.

now i am out of ideas.

I need help please

Part number for harness is : 61122410239, and in attach you will find original documentation.

I just got my harness and my Adaptive Led are on their way to me, hope to get them this week and I will update my post.

For coding part, I will try to code FEM with 552 (Adaptive Led) added to my VO and removed 522 (xenon). If there will be no result I will try other FDL codes.

Hope to get them work, and I will keep you updated.

Wish me luck!!!

Hi ,

Is this part no. wiring harness 61122410239 also applicable for our BMW M3 in right hand drive??


Thanks

Hi larry_bml ,

I’m interested about the original documentation you posted, because it states to apply to F20 post 03/2015 and F30 post 07/2015, but I’m a little confused.
I have a halogen F20 LCI (06/2015), and am trying to gather information to a future conversion to LED.

From what I see from your post history, you first converted a halogen F30 to xenon;
Later, you converted the same car from xenon to LED - is this right?

The document you posted doesn’t specifies to which conversion type it applies, but from the production starting dates it refers to, it should apply to halogen to LED conversions, because my understanding is that F20/F30 were:

F20 before 03/2015 and F30 before 07/2015:
- Halogen (standard);
- Xenon (optional).

F20 after 03/2015 and F30 after 07/2015:
- Halogen (standard);
- LED (optional).

Also, since the document refers installation of level sensors, it reinforces that it should be a halogen to LED conversion (since xenon cars already have level sensors).

But what baffles me is that the document states we should change some pins in the headlight connector - so use the same connector – but it seems the connectors between halogen and LED headlights are completely different, from pictures online that I’ve seen!

So I’m a bit lost here… can you clarify?
And any other recomendation is apreciated, too.

[larry_bml]

So, the document is for retrofiting from HALOGEN to LED, yes on my car that came with HALOGEN from factory I retrofited first XENON and after that, LED. I don't remember exactly all the modifications that I made, but first I advice you to start only with wire modifications specified in document, if you have HALOGEN. And if they are not working OK, then check ISTA wiring diagram again and see if there is any differences . Also if there you will find already pins inside the connectors of FEM where document say to attach new ones, just attach new ones over existing ones.
If I can help you more .... I will do it with pleasure, but first start doing it and we will see.

[tonirai]

Thanks for confirming, larry.

This will be a future project, as I still have BMW warranty and don't want to void it... but I'm very metodic, so I want to learn everything I can about this retrofit.

Some of my next steps will be gradually buying what I need for this, get my hands on a laptop to dedicate it to ISTA+... and learn all I can about programming (even if I later decide to ask someone to remotely do the programming part for me).

Just 3 more questions for now:
- Is it absolutely necessary to have the led headlight harness? Or can we use the existing halogen harness and redo the pinout according to the new Led requirements? Which do you recomend?
- When doing the programming part (VO changing, latest istep, etc...), is there a particular order to respect?
- Am I wrong thinking the headlight connectors are different size/form?

Thank you very much, I will keep you informed (though, as I said, it won't be for now).

Hello Larry please I need your help. i change xenon 522 with adaptive led 552. But after vo code fembody the leds doesnt work. Could you help me. Thanks advance.

I think only pin 9 and 10 must be connected. There is no male pin in led connector about 11 and 12.

Did you guys figure it out?
I want to do retrofit from xenon to lci adaptive led in M4, but don’t exactly know about harness, i studied wiring diagrams on newtis.info but they wasnt helpful enough.

Thanks

Bumping an old thread...

I'm about to swap my Xenons with pre-LCI LEDs. Can the coding be done via Bimmercode? Wondering what parameters to work with. Thanks

You can't do that with bimmercode.

if you need help can do that remotely.

cool, thank you for clarifying
