Was updating Evoque 2011 TD4's HVAC and now I get following Snapshot - I like to "downgrade" back to original BJ32-18D619-AH instead of BJ32-18D619-AK.
This https://www.freel2.com/forum/topic35187.html sounds very similar.
I am using latest version 164 and suitable HW/SW combination could be found in 2011_L538_2022...exml but how to do that forced update?

Maybe engineering mode?

Hello and thanks for pointing me on right track

However, “Module programming” was not present in versions 164 and 157 but I found it in version 138.

Then easy follow-up question - is my DTC fixed, if I download earlier file BJ32-18D619-AH to HVAC.
Is the LIN bus configuration “hard coded” inside the -AH file or is the software looking into the bus and then knows what nodes are present, and what to do with those?
If it’s like that, then why …-AK is not working?

At next I try to find installation files for SDD 138 and put that into Windows 7. Now I am running 138 in virtual machine - it’s quite slowly there because my laptops aren’t the latest ones  Evoque 2012, TD4

Managed to downgrade the software - well known "Software Download" was not working for me but decrypting exml file, change software version and encrypting again was successful. Still have something to do but software downgrade is not borthering me anymore ...

During the process I learned something about the SDD and if interested for somebody, I could write a longer text
