Hallo und ein frohes neues Jahr!

Nachdem ich lange gesucht, aber kaum brauchbare Information dazu gefunden habe, hoffe ich nun hier auf mindestens einen Profi zu treffen, der beurteilen kann, ob ich beim MIB II bleiben kann, und sich die Fehler ohne unverhältnismäßigen Kostenaufwand oder zweifelhafte Methoden beseitigen lassen.

"Was bisher geschah":

Ich habe einen gebrauchten Golf Sportsvan mit EZ 2015 gekauft, der zwar ACC hat, aber kein Bluetooth (Composition Colour, TN 510 035 867).
Da ich Bluetooth im Auto nicht missen wollte, habe ich ein MIB II mit der TN 510 035 869 C gekauft und eingebaut, in einer VW Werkstatt den Komponentenschutz deaktivieren lassen, per VCDS die Codierung des alten Steuergeräts übernommen, und zusätzlich Bluetooth Funktionalität codiert.
Die vorherigen Anpassungen habe ich, soweit möglich, ebenfalls übernommen.
So weit, so gut, Bluetooth funktioniert wie gewünscht.

Die Fehler seit dem Umbau:

• Anzeige "Front Assist nicht verfügbar".
  
• Start-Stopp und GRA/ACC sind ohne Funktion.
  

Hier ein Auto-Scan:
