sorry for the bump, i recently got the Burteq memory module for Octavia mk 4 https://burteq.com/products/octavia-4-memory-module?variant=48608674808132 based on the recommendations in this thread, and had it installed - it works perfectly. it basically saves your current settings (drive mode, start-stop on/off) and resets them every time you open ignition. i had it professionally installed, the installer told me its connectors are of high quality. it also features "service mode" in which you can easily disable the module with 9 clicks on a single driving mode
