Did anyone code the brake light flashing on the US version G20? Thanks.

Hi,

Try this in BDC_BODY (CAFD 7083):
Set GefahrenBremseLichht_Typ from nichtAktiv to bremselicht_blinkend

After doing this, if you stop suddenly, the third brake light will flash

Hope that helps!

Its a menu option on BDC on Bimmercode.

I have activated it and tested it and it works.

Pretty sure all brake lights are supposed to flash? At least that's what I've seen on various you tube videos and the like

You're talking about the brake lights flashing with turn signals.

This is to code the Brake Force flashing, where the brake lights flashing rapidly under hard deacceleration.

Figured I would join in on this. I have a 2020 G20 M340i and changed the GEFAHRENBREMSLICHT_TYP to the blinkend setting. Went out and tested it and nothing. Im guessing there has to be a considerable amount of braking in order for it to activate. Anyway to activate it regardless of force? I have seen it done on the F30.

FYI my general settings under the main ecu menu for BDC Brake force display is set to 5km/h and to weak braking.

I'm having the same experience. I changed the brake force display to aktiv and also on the 5km/h (weak braking) setting on the Bimmercode face module and tested with no flashing. Tried on my friend's g20 as well, also with no results. Interested to know what people did differently to get it to work.

Same thing for me. Canadian model and changed the GefahrenBremseLichht_Typ to bremselicht_blinkend and changed to 5m/s^2 and 10km/h break speed something like that and coded nothing happened after several test run. Not sure if north american model is not allowed? also my connector is OBDLink MX+

Don't quote me but I believe they might of removed it from the US/Canada spec models.

Some might notice that in just the last generation of vehicles, US-spec vehicles used to be fitted with a feature called "Brake Force Display" in the US; where when you stomp hard on the brakes, an additional area in brake light illuminates.

If you notice, that feature has been removed from the G-Generation of BMWs.

I guess the assumption is that brake lights being LEDs now, they are much brighter than halogen for the past, so BFD is not necessary or no longer implemented in some cars.

This might be the possible reason the feature is not longer available for coding, regardless if it's flashing or an enhancing brake light surface area.

Euro Brakeforce (blinking brake lamps) can be enabled in our NA vehicles but the only way I found was to VO/FDL Code the tail lights to operate like the Euro tail lights.

Everyone else that did it, even by VO coding, claims only the high center mounted brake light flashes, on NA-spec vehicles, not the lower left/right brake lights.

Where you able to confirm with certainty that all the brake light flashes, with a VO coding or region change?

Yes, I have confirmed. You have to code Euro tail light operation. Coding for my vehicle - https://g20.bimmerpost.com/forums/sh...7&postcount=55 or https://g20.bimmerpost.com/forums/sh...5&postcount=60


For jk1112 coding, but I do not know if he has confirmed correct Brakeforce functionality - https://g20.bimmerpost.com/forums/sh...1&postcount=69

Good to know and thanks a lot

If would humor me, just one other question; The older generation of BMWs had a separate subset of lighting in the taillights, that illuminates when US-Spec "Brake Force Display" (Area Enlargement) is trigged.

That expanded brake light area is what the ROW uses as "rear fog lights."

Since "rear fog lights" LED clusters do not exist in US Spec hardware anymore, I'm assuming by extension, the additional coverage of emergency brake lighting (BFD - Area Enlargement) no longer exists on the G-Generation of vehicles?

I think you are correct. I do not believe the G20 tail lights come with BFD-Area Enlargement LED clusters like the F-Series platform.

Is the flashing braking force only relating to the 7083 coding? Thanks.

As I have stated in my earlier posts, I only know of one way to get brakeforce to work properly.... code the rear tail lights to work like the ECE/ROW tail lights.

You have one of two way of performing this task as presented in my earlier post. Coding involves 7083 and 5665.

Just managed to discovered the setting for G22.

It's under BDC_BODY3, 3075 LceMaster. Not sure if it's gonna work, but surly just setting it via primary page on Bimmer code doesn't work.

Was able to code it on G05.
Only the 3rd brake light is flashing and it automatically disables hazard flashing after emergency braking.
