How do I code "Turn on tail lights with DRL"

[Lykke]

I would very much like to get the tail lights on with DRL. Dealer had no clue how to do this when I got the car :shock: , but I have since learned that dealers are coding this feature.

I have worked with this parameter from the coding cheat list:

Turn On Tail Lights with DRLs:
3062  MAPPING_TAGFAHRL_1_V_L_OUTPUT set to: tfl_l
3062  MAPPING_TAGFAHRL_1_V_L_OUTPUT set to: tfl_l

..but the car is already set to "tfl_l" and value "03". Today, without success, I tried to change the value to "04" as it seem to be the correct setting on other BMW models.

Anyone know what I need to code?

Thank you in advance

This is from an f30 coding guide. Have not tried it.

Thanks. I am not sure I have these options available, but I will give it a go when I have the opportunity to play around with the settings in daylight (..needed to test the effect ;-) ) I'll post result.

I don't think there's an REM module in the i3, but there is a BDC_BODY module — the 3063 Mapping_Universal rows might be there. BDC is where the rear fog settings live.

Hope it works out.

These values work on my i3 (shipped with i-level I001-15-03-502). The DRL setting in iDrive controls the tail lights as well.

BDC_BODY
3064 → MAPPING_TAGFAHRL_1_H_L_OUTPUT → sl_l
3064 → MAPPING_TAGFAHRL_1_H_R_OUTPUT → sl_r
3065 → MAPPING_TAGFAHRL_2_H_L_OUTPUT → sl_2_l
3065 → MAPPING_TAGFAHRL_2_H_R_OUTPUT → sl_2_r

Great, thanks!! Got to try that in the weekend

Coded the above values into my car ( I001-14-11-502 ) and it all seems to work perfectly Thank you very much I3

Can't seem to find any DRL settings in the i-drive though, maybe it not visible on my car. Where do you see that?

PS: I posted your findings to the i3 Facebook group and asked for it to be added to the cheat list

Glad to help. I researched other 2014/15 BMWs and tried their tail light DRL values. Worst case was just having to code back to defaults. Thanks for updating the Facebook i3 coding file - I've learned a lot from that group!

You should see a toggle for DRLs under:
Menu > Settings > Lighting > Daytime Running Lamps

-i3

Thanks again. My car do not have DRL options under Menu > settings > light, so that may be a country specific option or an update feature. But no worries; I want the lamps on ;-)

God job with reverse engineering of the codes. I think you are right that it is not really that dangerous as long as you make sure you have a backup or know exactly what was changed. So please keep up the good work
