Lane Change Assistant ( or SWA) on iX3 LCI
I have been working on LCA for a couple of months
I have read all the posts, especially about G05. All other coded functions works a simple question Is there anyone with the iX3 LCI model with working LCA ( Everywhere in the world and also with G01/02) ? |

I've written up the coding for it on another post here, not for the lci, but can't see why there would be any difference, got the traffic lights working as well.

Thanks the_ape I started exactly from your post !
I thought.. it's easy, let's do it The reality it's a little bit more complex. You are right when you say that to enable LCA coding required is : BDC_Body3 > CAFD_7083 > SPURWECHSEL_ASSISTENT Default: nicht_activ Change to: activ HU_MGU > CAFD_3E52 > SPURWECHSELASSISTENT Default: nicht_activ Change to: gen_1 SAS3 > CAFD_42C1 > C_SWA_VORHANDEN Default: Nr000_nicht_vorhanden Change to: NR001_VORHANDEN We can add that, if you have 8TR on your VO, it's possibile to achieve the same result removing 8TR and VO code Body3 MGU and SAS (to do this you can use esys without any luncher because it's not coding) ( thanks to ifr ) But.. in Italy LCA does not work. So I started playing with esys trace, testing different versions of VO (DE, IT and AU) to understand different configurations. I also tested code coming from G05 ( thanks to Bambazonke ). What I discovered is that all functions related to DAP are enabled by default. What really enable or disable a function is based on different lands. The differences between a base G08 (DE ot IT without (8TR ) and all other coding option are this : SAS3 C_SLA_aSLA_Land_aktiv NCD1: 0xF90F8600 (F9,0F,86,00) NCD2: 0xFFFFFFFF (FF,FF,FF,FF) C_SLA_Vorausschau_Land_aktiv NCD1: 0xFBDFA7C0 (FB,DF,A7,C0) NCD2: 0xFFFFFFFF (FF,FF,FF,FF) C_SLA_Streckenregelung_Land_aktiv NCD1: 0xFFCF9FF8 (FF,CF,9F,F8) NCD2: 0xFFFFFFFF (FF,FF,FF,FF) C_SLA_UCC_Land_aktiv NCD1: 0x08000000 (08,00,00,00) NCD2: Werte (FF,FF,FF,FF) C_SLA_QmaN_Land_aktiv NCD1: 0xFAC381F8 (FA,C3,81,F8) NCD2: Werte (FF,FF,FF,FF) C_SLA_aUCC_Land_aktiv NCD1: 0x08000000 (08,00,00,00) NCD2: Werte (FF,FF,FF,FF) C_RGA_Land_aktiv NCD1: 0x88880170 (88,88,01,70) NCD2: Werte (FF,FF,FF,FF) C_RGA_Seitenwahl_links_Land_aktiv NCD1: 0x88880170 (88,88,01,70) NCD2: Werte (FF,FF,FF,FF) PS1: where FF:FF:FF:FF it's necessary to get around "land control" Ps2: NCD1 value is the same for IT and DE configuration ( both ECE ?) With that coding it's possibile to enable, aSLA, TLA, UCC, Highway Exit Assistant, emergency lane, etc but not LCA. What happen when you try to use LCA is that the steering wheel from green become gray and nothing else. (I have to say that the same happen also for HEA) Summary . While it's possible to enforce some DAP options to work (es aSLA, TLA etc, with FFFFFFFF) seems not possibile to use the same procedure for LCA. But I'm sure I'm missing something...

Also the SAS changes are probably wrong. First 0xFFFFFFFF is (probably) not going to work because I think it means you are nowhere. No data for the land control, I guess you need to put the US code there. If the NCD1 is the same for IT (which is not supported) and for DE (which is supported), then that is not the one to change.
To sum up I think the NCD2 code should be changed to the German or the US value. Also I might be completely wrong! |

What i did one week ago 1) VO Coded the car as original 2) FDL only LCA 3) after that I coded also other options Now everything works fine In other words, it's possibile ho apply to G08 the same coding of G05 ( about DAP) |

Thanks ix3_Europa
Yes, I can confirm that works great ( now that is working..) The scope of my post was to clearly understand, country by country, 1) where is enabled by default 2) where's not enabled but possible to code ( es in Italy we have 8TR in VO) 3) where's not. Fullstop. For example, eTJA works only in USA and in Hightways. I tried to enable it but didn't work. |

I changed at my BMW iX3 following code: (Used Bimmer Utility)
Turn indicator 5x blink @ iDrive menu: H_MGU Turn signal 5x @ iDrive menu -> Disabled set to H_MGU Turn signal 5x @ iDrive menu -> Enabled Lane Change Assist: (Expert Mode in BU) Module to be selected from dropdown menu in expert mode of BU 7038 BDC_Body3 CAFD 7038 3420 PfSarahMaster SpurwechelAssistent -> nicht_activ set to BDC_Body3 CAFD 7038 3420 PfSarahMaster SpurwechelAssistent -> activ HU_MGU SpurWechelAssistent -> nicht_activ set to HU_MGU SpurWechelAssistent 300A SARAH -> activ (Gen_1) SAS3 C_SWA_Vorhanden -> Nr000-nicht _vorhanden set to SAS3 C_SWA_Vorhanden -> Nr001-vorhanden No country codes changed (Living in the Netherlands). By using above code changes SWA Lane chage assist is working. - When Turn signal is hold down for a few seconds the car start with moving over and turn indicator blinks 6x times (setting 5 times in the iDrive was more to go from 3 to 5 blinks w/o LCA activeted). - When a car is already passing you LCA will not work and the car passing you will turn into yellow. When no car is at the lane the BMW will start changing the lane. Next try will be traffic light assistance, when I cross the border towards Germany it will work w/o issue. Stop at red and automatic continue at green. |

BTW, I also changed "C_SWA_Auspraegung" There are three options: 1. Nr001_Variante_USA 2. Nr002_Variante_Cat_C 3. Nr003_Variante_LCI_SP2015 I tried #1 and #2. #1 is more aggressive than #2. Anyone tried #3? How about it? |
