    Controller refused to send a seed!

    deep look into our 5F adaptation session, when we captured a lot of UDS errors like read: 7F 22 31 (request out of range) write: 7F 2E 31 (roor as well) BTW: the requests are huge and nearly fourty CAN frames : 0x103 bytes payload in case of 22 0B 1D * and only once 7F 22 33 (security...

    ok, I just sent you adp maps and debug data from a different ECU that is not accepting my logins.

    Controller refused to send a seed!

    you need an adaptation map run without security access but debug level 1024? My fault, too many try and errors for me at once. :)

    Controller refused to send a seed!

    typo...I am not talking about a wrong login/SA but failing init of $27 secure access. I'd like to understand what happens. Is the requested SA level too high? I do not use coding but adaption channels. See my initial post.

    Controller refused to send a seed!

    I tried like 20301 and that special S12345, but as the ECU refuses the Seed-Generation (which comes before checking SA correctness), it does not matter what I try!

    Controller refused to send a seed!

    this is my main goal: to understand why is MIB3 saying "Controller refused to send a seed" Err:12. If you google it, it's quite common for ABS access and other ECUs, but it has been fixed somehow or the error subcode wasn't 12. If it's clearly pointing to a SFD* topic okay, I would accept, and...

    Controller refused to send a seed!

    it's an Aptiv MIB3 Premium device J794 under the hood having the same bugs and behaviors like Audi, when they introduced it in the A4 2019 Is the refusal of a seed really unknown in the rest of the supported VAG world?

    Controller refused to send a seed!

    is it possible that a diagnostic firewall is enabled and therefore the strange seed refusal? I compared the above procedure with an Audi 2022 Q5 with MIB3 infotainment and I was able to read all adaption channels without any "secure access" warnings after disabling the firewall.

    Q3 F3 - Garage Door Opener

    is there any reason to place the retrofit ECU in the rear, rather than to find a position close to the BCM in the front of the car? why the heck did Audi place it at the rear?

    Debug level

    debug=2 is only valid for Auto scan? So basically the same as doing a controller channel map scan for "whole vehicle" UDS/CAN? https://www.ross-tech.com/vcds/tour/controller-channels-map.php
