DIY: Coding for OEM Xenon AHL Pre-LCI to LCI Headlight Conversion
I kept coming across comments suggesting there are numerous articles and DIY's available on converting from pre-LCI to LCI Xenon Adaptive headlights but I couldn't find any such useful technical information; specifically, coding procedures.
Hence the creation of this DIY: to provide detailed, step-by-step coding instructions for various scenarios encountered and personal preferences when converting from an existing pre-LCI Xenon AHL headlight system to an LCI version. This conversion was performed on a 2008 335i Sports Package AT with Xenon AHL's and FRM2 module as standard equipment. If your vehicle is not similarly equipped it may require additional components and/or coding to complete the LCI Xenon AHL conversion. Also, used ALC modules were installed; brand new ALC modules may require initial "flashing" or programming of the VIN prior to coding, which I have never attempted. If you are planning on upgrading your Angel Eye bulbs to LED, it's best to do this on the LCI headlights before installing them on your car; it's much easier than trying to properly index the LED bulbs into the sockets and then squeezing huge heat sinks into the cavity all in the tight confines of the engine compartment. Be advised, the upper corner 3-LED marker lights will not be functional unless you provide a power source to pin 7 of the headlight harness connectors. Many people disable these LEDs anyways by coding them off, so if you are one of those that dislike having them on when your headlights are on, rejoice as no further coding is required. Parts Required Set of LCI Xenon AHL Headlight Assemblies
Tools Required
You should already have the necessary software, hardware, and at least a basic working knowledge of coding the E9x platform. I'm using a 64-bit compatible INPA/NCS Expert software package on Windows 7 x64, however, I will not provide the software nor links to same so please do not ask. There are sufficient sources and information available on this forum and elsewhere, which are all subject to constant change and thus beyond the manageability of this DIY to keep links and references to external content current. Headlight Removal and Replacement Procedures Step 1: Follow the attached "HL_INSTALL_B3_E90" PDF for physical headlight replacement (credit goes to SpeedsterSource.com for that DIY), with the following suggestions:
Step 3: Place the vehicle in park and shut down the engine while leaving the vehicle power on (unless you are not yet prepared for coding). Initial Coding Procedures For consistency, the descriptions of module settings are from NCS Dummy when applicable. The firmware versions of my vehicle were as follows: NFRM = FRM2_E89.C09, LSMC = SMCDS_LI.CO7, and RSMC = SMCDS_RE.C07. Thus, the settings described may or may not be applicable or different for your vehicle depending on its production date, Vehicle Order (VO), and firmware versions. Step 1: Attach the DCAN cable to the ODB port of the vehicle and USB port of the laptop. A status LED (if incorporated) on the adapter body should light up confirming connectivity to the vehicle. Step 2: Launch NCS Expert Tool. Step 3: Follow the attached "Coding the Front Turn Signal Lights" to disable the bulb checks for the front signal lights. You can use the included "NCS Dummy profile" if you don't have the "Expertmode" profile. Summary of basic settings manipulated (for experienced NCS Expert coders):
Additional Coding Procedures Resetting and Coding a Used ALC Module to Correct Directional Aiming If one or both of your used ALC modules are turning their headlights opposite of the steering direction, then follow the attached "Resetting and Coding ALC Modules". The profile "Expertenmodus (Werkseinstellung)" is included for performing the reset steps, while the "NCS Dummy profile" is used for the coding steps. Summary of basic settings manipulated:
Optional Coding By now you should be comfortable reading, changing, and writing ECU modules. This list contains useful codings for optional features and basic management of the Adaptive Head-Light system. Side Marker Lights
Angel Eyes as Daytime Running Lights:
Adaptative Headlight Settings:
The BMW E9x Code List v1 has also been provided for reference. Good Luck and Happy Coding!

Hi. Very nice diy.
But... H3 isn't drl bulb. That bulb (inside lights in headlight) works as cornering light. I've done that retrofit from prelci halogen to lci xenon ahl. Everything ok but can't get cornering lights work. Does it works on your car? I've got couple different questions if you don't mind. Thanks for the diy.

Sure, ask your questions!
And H3's definitely the type for the DRLs because I changed those out for a pair of MTEC's, even though I programmed the halo rings to activate as DRLs. Funny thing about the programming, the DRL's now activate as the "flash" beam when pulling back on the turn signal stalk instead of the high beams; the high beams still activate when pushing on the turn signal stalk.

I just noticed you're located in the UK, so nomenclature of various lights may differ from the US. Here, the Daytime Running Lights for the OEM LCI Xenon AHLs are the inboard headlamps that have louvred lenses.
Depending on BMW model, the "cornering light" could be the fog lights or the inboard headlamps. Activation of the cornering lamps should be done through coding of the NFRM module, but of course, would require the steering angle sensors used by the AHL headlights; not sure if your car is equipped with that gear or if you retrofitted it as part of your halogen to LCI Xenon retrofit.

I retrofitted that wiring too.
http://www.bimmerforums.co.uk/forum/...ahl-i3gvx4.jpg Cornering -i mean no2 on the drawing. Can you check what direction is for yours. That's very interesting. ... Edit: My headlights identical as them: Drl with ae's stronger than parking lights. You can see cornering lights too. Everything works same but I don't have cornering. Did you add +MUEG to the VO?

I personally did not enable cornering lights in my NFRM module as they don't really add any appreciable value being unable to swivel into the turn, and since this feature is not commonly used here in the US (I've never seen a late-model BMW have them enabled) it would look rather confusing with only one side coming on while turning (the turn signals already serve to indicate to others the intended turn direction). Quote:
I've also installed the DTEC v9.5 for the AE bulbs and Osram D1S for the Xenons and both are fantastic; pretty much as bright (if not brighter) as in the video clip. I'm not familiar with the "MUEG" option, but regardless, I didn't have to change my VO because I already had Xenon AHL's in my pre-LCI, so swapping in LCI AHL's was relatively painless (except for the higher cost, which was offset by selling my complete, pristine pre-LCI Xenons). Everything works as expected, except the top rear corner 3-LED light, which requires running a wire from the headlights to the FRM module (which I plan to do when I retrofit the newest NBT nav/iDrive system into my car).

Hi I've just bought an E92 which has had the LCI front and rear lights installed. I followed the guide but my angel eyes are just flickering in every setting then turning off. Ideally just need someone to tell me what needs to be done not do it for me.

I did the same and the AE's doesn't have the dimming fiction. They are always in the same low brightness Maybe that's the low pwm voltage from the pre Lci coding ? I don't know what's wrong I am on frm2 Maybe I need to code something? Hope someone can help |

I know this post is really old but I kind of need help. I found a set of LCI Xenon lights for 1800SEK which is like 180$... Really cheap. I am most likely going to buy a E91 tomorrow, which is a build date somewhere around 08/08. As I understand this car should have a FRM2 module? Does this mean it's plug and play and only coding? The car I am buying has Pre-LCI Xenon Adaptive Head Lights.

It should be plug and play. I went from pre-LCI halogen to LCI xenon. I used a FRM from a pre-LCI adaptive Xenon equipped car and programmed it as such (identical programming to a pre-LCI xenon car but without the adaptive function enabled), and it controls the LCI xenon headlights just fine. You may need to code out bulb checks for the turn signals, though I'm not sure. I assumed because the LCI headlights use LED turn signals they may throw bulb errors. I just disabled the bulb checks and it's works great. |

Also I have no car since the car purchase went to hell. Travelled with plane etc to another country just to have the dipsh*t be a jerk. Though! I found one in my country and he's willing to sell it somewhere around 6months time, maybe a little less. E91 335i with all the options wanted, -07 though with production date december 2006 so might not have FRM2? |

FRM2 allows you to use the ring lights as DRLs. On older FRM versions you're left with the inner pair of lights as DRLs, but in the US at least they're not mandatory so I turned them off. |

E91 xenon to halogen
Good afternoon,
My wife has an E91/320D touring from 2009/10. Both headlight lenses have been cracked or broken in the last few months, they are Xenon but came with the car so not sure which type they are. She isnt fussed on xenon or halogen so i took the cheaper option and got a new set of halogen headlights. Succesfully removed old ones and replaced with the new units, everything works except the high beams on both. I get high beam indicator on dash cluster when triggered but no high beam. No other error messages on car monitor or with INPA. I am guessing i need to re code the ecu back to halogen settings but have not been able to find any info on such, only for upgrades! I have PC laptop running windows 10, KDcan cable and the BMW tools downloaded already. Can anyone help with this? Thanks in advance! |
