Does your Climatronic or climate controls support front windshield heating? what I'm trying to say is, how are you turning on/off the function?

I made this Excel sheet based on comparison of ELSA and my model year & features, it can and should work for others to retrofit too. There are other info there too. https://www.aliexpress.com/item/32275028179.html?spm=a2g0o.productlist.0.0.64b94219TR7Ep0&algo_pvid=0601ab18-c4c5-4c3b-8715-4ad7b88e0fa5&algo_expid=0601ab18-c4c5-4c3b-8715-4ad7b88e0fa5-0&btsid=c55f559b-4e71-464a-99a7-108c3a35776b&ws_ab_test=searchweb0_0,searchweb201602_7,searchweb201603_52 These are the turn/drl lights that I have installed but DRL are currently wired on a toggle switch until I incorporate them into the BCM to work as factory and the turns are wired into the factory harness and work as factory turn signals. The DRL do turn off when the turns are selected. My car has AFS/bi-xenons and are wired to C48/C49 and position lights to C26/A44 as per ELSA B7, but position lights are in Bi-xenon headlight assembly for B6 as you know. This is why I wanted to change light config for DRL to A3/A4 to use the DRL in the new Turn/DRL lights. Passat B6 CECM to B7 BCM.xlsx

I would love to learn more about your findings of the BCM and light configs if your willing to further discuss it. I am not a VW or Passat or electronics beginner but am a beginner in this BCM, I do know enough info to get going. I know that I have a fended several people here on this forums with bringing english here and I'm sorry. I can translate the info but didn't want what I was saying lost in translation. I have the means(computer & programs) to do the work and how to use most of it.

You once posted a "byte18 pdf" link, that link I have seen before but they send us somewhere else. Do you have this pdf that you can send me? How were you able to get the bcm1 of the 0B coding without the BCM? Or did you load that code into your BCM and save the lighting config? I will work with the file you sent and make do with that, Thank you so much for what help you have given me.

It does work as I have already done it to my car which I have went from 3C0 non-kessy to 3AA Kessy. I just had to get new keys and match keys to CCM. I am currently using this 3AA kessy that was transferred and all is working correctly.

That's exactly what I was going to do but don't know what else is enabled/disabled with "0B" coding for front lighting. I also wanted to activate/use A3 & A4 for DRL's as I have B6 turn signal/DRL combo installed. I do not quite understand what "0B" coding means - 0B VW364 RL Halogen VW364 RdW TFL_0 RL ROM 11 VW364 VW364 RL halogen RdW TFL_0 RL ROM 11. Does this coding support B6 AFS, flash to pass, high beam shutter, and front & rear fogs? I see that 0B has TFL_0, doesn't that mean no DRL? I think there is another coding that is better to use but I do not understand what coding supports what and for B6/B7 variant.

Yes, my mistake B29, but still same issue with this B29. then with byte18, is there a way to activate the front fogs, flash to pass, and high beam shutter? I am from the US and yes coding is US version and I am currently running euro version driver rear fog light. I do want to continue to run the rear fog light if possible. The 087R module is from a donor US CC and don't really know what was equipped on this donor car, but can use this light config and make adjustments to work for me or adjust the 087J light config and stay with that.

I didn't get the light config from the 087R but will do. Pin C29 is used for Terminal 50 signal to starter since CECM and early BCM's only using J682 starter relay, Later B7/CC moved to two starter relays(J682 & J710) and in this case the terminal 50 & terminal 15 signals merged and the one click start is used now and also in conjunction with start stop.. This also means that terminal 50 is constant switched power of terminal 15, so pin C29 is no longer needed. I will look into the light config changes you made and get back with the 087R light config. Byte 18 can be changed and needs to be changed for the forward lighting then alter eeprom for rear B6 lighting. All BCM's have a coding for Byte 18 but almost all BCM's show 00 for coding. Now with coding Byte18 and then changes to eeprom for rear lighting, the coding will show 00 in the end result. This is the coding shown when testing 087R - 0008000000000000008802819400094C20550B0840200D20E484402400C0. As you can see 0B is the coding for byte18, this coding rom is not correct for my car but its a start. I'm hoping that someone can help me better understand what coding can help me or what coding to start with.

I know that I'm late in this topic but I have retrofitted 3C0 CCM to 3AA Kessy CCM and the immo/CS info can be transferred from 3C0 to 3AA but only need kessy keys and kessy harness & antennas. Kessy door handles are the same for B6 & B7, there is no difference. There is also the start stop fault code when retrofitting CECM to BCM. 08+ door modules work with 3AA but have safe lock issue.

I only tested 087R but did not make any light config changes as I know 087R does not have C29 pin for start so waiting to install pin & resistor so car can start before making lighting config changes. I want to sort the byte 18 coding and lighting problems before moving on. I do not know which byte 18 code that I should use or what code I should start with, with the lighting equip that I have. Pin C29 is in BCM's from 087 HW 413 to last 087(x) with HW 421, as all BCM's with 087(x to R) HW 422 does not have pin C29.

Test 3 B6 BCM light setup.bcm1 I do not get any errors for fog lights, flash to pass, and rear fog light. They just don't work when switched on. I have also a 087R BCM and it does work the lights but it needs to have the pin C29 & resistor & light config done added to use that BCM. if you can send that file for SW update to work with 087J 421 0465 to 0475 that would be great.

nTomek, Sorry I don't speak Polish but have been translating this site to help me. Hopefully you can help me. I have converted CECM to BCM using 087J H++ 421 0465 and have used VCDS, ODIS, VCP, and VagHelper to get everything working, which does now but problems are - front fog lights, High beam, flash to pass, and rear fog light do not work. LHD MY08 3.6 4motion Variant equipped with xenon adaptive front lighting with corner & headlight range control module, front fog lights, and driver rear fog light. Current coding on BCM - 000800000000000000880281B400098C21F5000843210D236484C1000040. Also can you please provide more info on flashing BCM to 475 software. Did you rename the file with name of current BCM to work? I would like to update mine from 0465 to 475. Thank you for all advice that can be given.

There is a person named 46otdmil who has made a emulator for this coordinator issue which should be the answer to my problems but he is on Drive2 and the system is down to sign up for that site. Do you know of this person and if so do you have any contact?

Not true as I was able to start the car with the button and as stated no start stop from factory in car but that was wiring completely based on B7 so on B6 starter will stay engaged. Wiring mostly on B7, B6 electronic ignition switch works as should but with button gives one second of power to terminal 50 so no start then. This is where I'm stuck at as trying to find a way to hold down button to work as switch. Now there are other people who have completed this but either don't remember/lost info or can't sign up for Drive2 to contact others who can help. So i'm turning here for help.

2012+ Passat B7 & CC require brake pedal to be pressed to start but not 2005-2011 Passat CC & Passat B6. MY08 does not require the brake pedal to be pressed to start. My friends 13 CC has the same BCM as me but does not have start stop and no fault for start stop coordinator but I do and I have compared coding with mine. What I'm asking is can I code or adapt out start stop? I do not have start stop anyway.
