M4 LED's vs 340 LED's

I saw an M4 on the road today while driving and the LED's on it seemed very bright and noticeable - both the angel eyes and the LED headlight. Does anyone know if they are brighter than those on the 340i? It could be the same but for some reason it looked much more noticeable.

I dont have exact info on if its brighter or not but i too did notice that the lci led angel eyes seemed dimmer or more cool blue in look. Both M4 style and lci are bright but i think they are different in light temperature making them different in color.

It is possible the other car had lights that had been coded to be brighter.

There's an was test if you just get an F30 and an F32 side by side.

I'm 99% sure the 4 series LED lights are brighter than the 3 series LCI ones.

The reason being, in Europe, the 4's LEDs require washers whereas the 3's don't. The only reason for this would be that the 4's output more than 2000 Lumens which is the start of the legal requirement for washers. I'm waiting on confirmation of this from BMW.

That sounds interesting. Any idea how to do it?

That sounds very strange. : Why would the headlight output be less lumens on a newer model?

Angel eyes on the F30 LCI are dimmed to 46% intensity when the low beams are active. The coding mentioned in the Cheat Sheet you linked does not apply to the LCI LED headlights.

does that mean the LCI currently doesn't have the ability to change the DRL brightness via coding?

No, it simply means that the coding is completely different for F30 LCIs with the new FLE ECUs

To bring angel eyes to 100% intensity when the low beams are on, try changing the Werte values for POLI1_Idx, POLI2_Idx and POLI3_Idx in each FLE from

01, 01, 01, 07, 01, 01, 08, 01, 01, 01

to

01, 01, 01, 07, 01, 01, 06, 01, 01, 01

If you code one FLE at a time, it will be easy to see the difference.

Note: The above is for US-spec cars with adaptive LEDs (SA552) only (I have not checked whether it applies to the non-adaptive LEDs). The coding is different for Euro-spec cars.

So just the angel eyes are dimmer? What about the low beams? I wonder why BMW would do this.

Hmm can someone check this out and see for non-adaptive cars? Thanks!

The low beams on US-spec cars (with VLD disabled) are always on at 100% intensity and only very slightly dimmed when the high beams are turned on.

The angel eyes are dimmed by default when the low beams are on even on pre-LCI cars (with Xenons or LEDs). This might be done to meet the strict ECE regulations regarding maximum low beam light intensity.

On my xenon headlines, the angel eyes dim when the low beams are on too. When the low beams are off, the angel eyes are brighter. Seems to be the same with LED's, which is a design by intention I guess.

Coding is magic. Any risk with coding?
