Do you have the latest PsdzData?

I'm using 4.21.21 - Which I grabbed in December and was current as of the I-Step version. What's the latest?

If they have coded it out for certain regions, there has to be a legitimate reason. I would think stringent regulations are not being met, or something related to potential litigation issues.

If you get in an accident as a direct result of you enabling a feature that was not intended to be enabled for your region, is BMW at fault? Even though your BMW just steered itself into another vehicle?? I don't think so...

I used 4.22.14.

That "legitimate reason" is usually pure marketing decisions.

If the hardware is there and functional, coding it on or off (like disclaimer nags) isn't dangerous. FDL coding is like changing registry entries in a Windows PC. It's not the same as VO coding, which attempts to tell the car it has something it may not.

Face it: today's cars are platforms with wheels to keep the computer from scraping the ground. People are going to experiment with them as a hobby.

Thanks. I'll try that version today.

HUH?? You are countering your own observations here:

I realize BMW has turned it on starting, I think, with G05. When you consider that the Massholes around here will rely on this too much, it makes you want to stay home. Beware current BMWs that change lanes near you.

The two posts are completely consistent.

People will turn it on and use it using the same logic that makes people ride on 21" summer tires in Boston winter weather.

Do you think that the warning the wheel seller give the buyer telling him he's insane makes any difference?

I am pleased it (appears to be) hard to code. That's not going to stop a substantial number of Massholes from doing it and crashing. But it doesn't mean BMW had a safety reason to code it off especially when it's the same hardware and software functionality (presumably) worldwide.

I will look over my old backup codes and see if I can remember what specific items changed for that to work. It didn’t automatically change though, it would alert me if the speed limit outside changed, and then I could press the rocker switch on the steering wheel and it would adjust.

Any luck on the ISA? Thanks for sharing the Lane Change Assistant code BTW

[AcidLotus]

Perhaps someone can help. I see the following settings for SAS2 on a U.S. 2020 G01 X3 M40i and what they are currently set by default from factory:

- Under 3000 SAS_10, FC
C_AHM_vorhanden: false
C_aPDC_vorhanden: true
C_HDC_vorhanden: true
C_Segeln_vorhanden: enable
C_LCA_vorhanden: true
C_EDP_vorhanden: false
C_EDP_Land_aktiv: 0xFBDC0000: FB,DC,00,00
C_STA_ALC_Vorhanden: true
C_Segeltempomat_vorhanden: true
C_ISA_vorhanden: false
C_AWA_vorhanden: true
C_LCA_rSKW_Vorhanden: true
C_LCA_SKW_Vorhanden: true
C_LCA_SVW_Vorhanden: true
C_LCA_SWW_Vorhanden: true

- Under 3001 Umfeldmodel, FC
C_VZA_Funktion_Land_aktiv: UNK_PARAM_1: FB,DF,83,C0
C_vSLI_Land_aktiv: UNK_PARAM_1: FB,DF,83,C0

I'm also getting Kommentar=Trimmed Function on all of the HU-MGU Funktionen. This is with psdzdata 4.22.14 with e-sys 3.28.1 with Launcher Pro 2.8.2

Are you able to find out what item changes are needed for the ISA? Looking forward to it, appreciate!

[pacokie]

Thanks for the information！
However it seems not working on my 2018 G02 X4 with ID6 and 5AT. (Taiwan)
As I know ID7 is more possible to work, while there are advanced feature like extended
traffic jam and detecting cars in 3 lines.
Or someone says maybe 8TR which also blocks this function should be also removed?

[sinbad4]

Anyone get this working in 2020 X3 w/ iDrive 7 yet?

FYI, after the coding is done make sure you are on a road which has a median / barrier between oncoming traffic.

This is a requirement of the system, it wont work on roads that dont have a barrier between the traffic.

although i have a 2019 with ID 6

Thanks for the information! Do you have 8TR (or removed)?

I do have 8TR, no need to remove it.

In my 2019 G01 X3, just the coding mentioned by the OP

- it will work on the X3 with either iD6 or iD7. While BMW gave the 2020MY cars the newer headunit and cluster, the Other modules remain the same. The only difference you will find is that changing the code on the MGU headunit on iD7 adds a new option for the lane change assist in the settings menu, but it won’t let you actually check the box. It still functions fine however.
- I am not sure which values correspond to which countries. User ifr is the one who informed me about that piece of coding, I just changed it to all FF like he recommended, and it worked.
- If you are having problems with trimmed cafd files, I believe that means you need to update your psdzdata, or your esys version, along with your program of choice, either esysx or ProLauncher.
- If your car has the Driving Assistant Plus, which is required for the Lane Change Assist option, you most definitely should have a SAS module.

Thanks heaps for the details mate.
Coded this today but no luck. I'm in Australia. Anyone got it working here?
My car is 2019 G01 X3 with 5AT- Driver Assistance Plus. I-Step S15A-20-03-540.

No reason this isn't working in Australia. Confused now...

[jimmmyzhou]

Can confirm it works on my G08 2020 X3(CN version of G01). And it's also possible to change the default above 70km/h triggering speed. It's also in the SAS module. Thanks for sharing!

Can you specify what the code is to reduce the speed limit?

Off topic but just some friendly advice - change your username NOT to be your e-mail. You never know what's out there scraping for e-mail IDs - and if you use that address as primary then it helps not to broadcast.

Tell me to mind my own if you like :->

I found an option with 70km/h and suspecting this was the triggering speed for LCA, and change this manually (hex value) will change the trigger speed of LCA
