High beam assist cannot be reached problem.

[Ivan.p]

Hello everyone,
I know that this topic has been discussed many times, but I do not find the information I need.

I have an audi a3 8p, 2012.
I'm trying to retrofit a high beam assist mirror. What I have available is:
My old can gateway from my own car: 7N0 907 530 N
HBA mirror: 8K0 857 511 E
extended can gateway (I bought it from a scrap car): 7N0 907 530 Q
momentary stalks.
I am trying to connect the mirror to the can gateway, pin 3 of the mirror, I have connected it to pin 16 of the can gateway module.pin 8 of the mirror is connected to pin 6 in the gateway module. The cables are a twisted pair. When I encode the can gateway module with VCDS, I select 20-high beam assist in the installation sheet. And in the bcm module I encode on byte 11, high beam assist installed. After scanning with auto-scan I get errors in the gateway module, in bcm and in the high beam assist module. In the can gateway the module writes to me that there is no communication / signal with the high beam assist module. The bcm module tells me the same thing. And on the high beam assist module it says: status: cannot be reached 1100. But there is one big one, but when I enter the select module and select 20-high beam assist, the module loads me, and I can encode it. But it doesn't really work. Does anyone have any idea what the problem might be? I tried a lot, but nothing worked. I look forward to your advice. Thanks in advance.

8k0 is not the correct mirror for a start iirc, subject to checking etka.

Did you connect to the correct bus, iirc it's the drivetrain bus.

Yes, I know this is not the right mirror. The correct mirror is 8p0, but I could not find one, hoping that it will work and there will be no problem, I bought 8k0. I think I tied it in the right places, but I'm not sure. 16 pin and 6 pin from the gateway connector. With VCDS I manage to access the hba module and change its coding, but I fail to activate the assistant, high beam assist: systems fault appears on my dashboard. And when I start auto-scan, I get an error that it can't be accessed.

PS: the HBA module is coded with a distance monitoring assistant. And I think if it is coded not to have this assistant, will it work? If anyone has the opportunity to help with coding?

 

[Ivan.p]

I am worried whether the hba module is connected correctly to the can gateway, because in some schemes it says that it should be connected to 7 and 17 pins, and in others to 6 and 16 pins. Can anyone guide me? Also now I checked the measuring data block of the high beam assist module that the bcm module does not communicate with the mirror. When I turn on reverse gear or the lights, nothing changes there. Attaching a photo

I'm posting log file from auto scan in vcds. Any hope it will works?

Did you also check in this thread in the TTforum for the coding required?

I bought the right mirror, 8p0 and now everything works perfectly. I only have one question, because I want to connect 6 pins of the mirror to the lighting ceiling, so that it does not get dark in the evening when the lighting is on inside. The socket on the lighting ceiling is 12 pins, I found that it should be connected to pin 1, but there is no result. I will attach photos of the socket, which is on the lighting ceiling. I will be very grateful if anyone can help me.
