I have LED angel eye without resistor. The monitoring of the car says he lamps are defective because of the low power consumption.

Is it possible to code out the warning on the defective lamps?


E90 LCI 09


and E92 07

Bumping an old thread. I tried this technique but once the engine is running the voltage drops by around 1.5v. Any ideas? I programmed for 10.7 volts, which works when engine off perfectly. But once I start the car it gradually drops to 9.

Did you code out cold and warm checks?

Yep. I'm trying to control the pwm for e90 prelci inner and outer tail light bars. going to give it another go today. I reset my frm to factory and I'm starting over.

I noticed in new modules where native led lights are present pwm is ruled by percentage and not by voltage. I'm not sure if that's available in FRM1 and FRM2.

I was trying to figure out my hid issue and saw this thread.

The previous owner tried to code the car i guess so but i wanna do everything from ground zero. So how do you go reset the modules to factory settings? I tried with empty NETTODAT.MAN file but it didnt work

Try this. Password is b m w c o d i n g. c o m minus the spaces

empty the fsw_psw.man also and sg_codieren the module

Guys, sorry to bring back an old thread, but it seems the most relevant.

I have an E91 LCI with bi-xenon lights (Euro model). My angel eyes are on as DRLs (that's stock). The car has a FRM2 with coding index 09. When I change PWM_SL_V as per the first post, it only controls the brightness of the little LED corner light, not the angel eyes. Any ideas on how to get the angel eyes brighter when they're in DRL mode (i.e. headlights off)?

You have to code via NETTODAT to achieve this.

Okay, so do you have the specifics? Like which byte, what values, etc? (or just give me the textual name, eg. PWM_SL_V, and I'll find out which bytes correspond to it... but I still need the new values to write). Thanks.

from the beginning and you'll see what you're looking for on the first page...

I did read the thread, incl. the first page, and there's nothing there that applies to my case. The settings they talk about there are not available in the FRM2 (other than the ones I already tried, which as I said control the side marker LEDs and not the angel eyes on my post-facelift, Xenon-equipped car). One thing that I did see on that page is that stuff containing "RL_BL_1" may control the angel eyes, so I tried PWM_RL_BL_1_FKT_PARKL and boom, I can change the brightness of the angel eyes when the parking lights are on. I can make them as bright as the DRLs. I also noticed that turning off DRL_TFL_MIT_RL_BL_1 turns off the angel eyes as DRLs.

But there's no setting to change their voltage when used as DRLs. I tried PWM_RL_BL_1_FKT_SL, but that doesn't seem to change anything. Any ideas?

I also wasn't able to increase my brightness using custom 13.7 value on my 09 e92.. Tried all of the coding options seen on these threads with no visual change. I'm stumped

Are you bulbs compatible with voltage variation? If they have a dedicated driver then it doesn't matter if you choose 1300v the bulb will only get the default 12v.

Do you have PWM_RL_BL_1?

I believe this was the setting on my 09. NCS Dummy describes it as for taillights but it works for angel eyes.

Take a simple example - say you've got a bulb that has three 3.7v LEDs in series connected to a 12v source and doesn't have a driver. The result is about 4v across each LED, meaning they're overdriven and will be okay but at the cost of their lifespan somewhat. If you were to code the voltage for that bulb up to say 18v, you're now talking 6v across LED. If it didn't kill them instantly, they'd be dead in hours at most.

But, say you've got an LED bulb that has a handful of LEDs but uses a constant current driver with a reasonable range of input voltages. No matter what you up the voltage to in coding, the driver is going to just adapt and send the LEDs the voltage it's set to - they won't get any brighter and they won't get hurt. What will happen is the driver will be generating more heat from the upped voltage.

The takeaway from this is don't mess with the voltage of any LEDs unless you know what the LEDs are rated for, how they're cooled, and how they're being driven.

Interesting, thanks for the quick lesson!

But what about the converses; lowering the voltage on a LED bulb with a driver/resistor? I have LED fog light bulbs and they're extremely bright. I've been wondering if I find a PWM control for the fog lights and change it to a lower voltage, will it theoretically lower the output of those LED bulbs?

[PeterFaludi]

Does it increase the tail light brightness also? It should be, right?
PWM_RL_BL_1_FKT_SL
PWM_RL_BL_2_FKT_SL
Doesnt kill this increasing thing the FRM module? Through the FRM modul the Voltage will be higher than it was, wont kill this the module?

Does anyone know if this actually helps to increase the brightness of the outer lens?

I tried this and I didn't see a difference in the outer lens. I'm just wondering if I did something wrong.

You'll never get the outer lens brighter. BMWs shitty design to blame for that. I'm assuming you're talking e90.

This is correct.

The headlight and angel eye light source biases the inner ring. There is no way around getting the outer ring to light up more other then going with custom angel eyes.

Thank you for the clarification! I appreciate it. On a side note I hate the way the Pre-LCI E92 headlights were designed haha.
