Licence plate light brightness when backing up

Toshi_BMW · Apr 7, 2015

Hi guys,
It's been a long time here.

Is anybody frustrated with rear-view camera image at night? I found license plate light sometimes causes terrible glare (whiteout) in the image.
These codes enable you to control the license plate light while you are engaging the gear selector in position "R".

[REM] MAPPING_UNIVERSAL_2_OUTPUT Werte=00(off) >> Werte=22(kzl)
[REM] MAPPING_UNIVERSAL_2_PART_OF_WL not_active >> hard_on
[REM] MAPPING_UNIVERSAL_2_FUNCTION Werte=0C(bremslicht) >> Werte=0F(rfs)
[REM] MAPPING_UNIVERSAL_2_PRIORITY Werte=02(priority_2) >> Werte=00(priority_0)
[REM] MAPPING_UNIVERSAL_2_FIXED_PWM Werte=00(pwm) >> Werte=01(fixed)

To adjust the KZL (license plate light) brightness, change the following value in hex.
[REM] MAPPING_UNIVERSAL_2_PWM_LEVEL_1 Werte=00(off) >> Werte=00 to 64(100%)

*You may use "UNIVERSAL_3" or above if "UNIVERSAL_2" is allocated for another mapping.

Nice!

Hello Toshi,
Nice!!
What bothering I the most about 4-series was the dark rear view at night.
This coding stopped bothering me.
Thank you.

No problem at all :thumbup:
Seems nobody except Japanese cares about this?

Hello!

Thanks for sharing. I had a t minimum three guys here with a white F11 which are really angry about an unusable rear-view camera at night. The codes are for F20/F30 and I will check now whether the codes are also available for F10/F11.

Please share when you find the similar mapping codes in FRM!

Nice job!

Could you please explain what these codes actually do (code by code)?

Very simple

_OUTPUT = which lighting you would like to code mapping
_FUNCTION = trigger to activate the map
_PRIORITY = 0 means highest priority.

I think I don't need to explain these.
_PART_OF_WL
_FIXED_PWM
_PWM_LEVEL

Hi Oliver,

Have you found anything for my white F11?

@Toshi_BMW,
So this will allow you to either increase or decrease the light coming from the license plate lights when backing up -- more if it is too dark or less if you have glare by coding the MAPPING_UNIVERSAL_2_PWM_LEVEL_1 -- is that correct?

Will that work on my 328i (F30)?

Thank you very much

Hmm... I don't think you can increase the brightness more than 64 (=100%).

Wow. This is great news. I have a useless 4 series backup cam. Hope this helps.

Glad to help you :thumbup:

Thank you so much Toshi_BMW !!!! My rear view camera operates much better at night on my 2018 M3 - Alpine White. This is the most useful FDL code DIY out there.

Good to hear that.
Now I've been struggling to find the codes for G15 but no clue at all...

Thank You for the codes, it works well.

I was wondering, what are the other possible _FUNCTION triggers?
Instead of "reverse gear", something like "backup camera" or just "PDC" would be even better.
