Trier to Woffelsbach is more like 130km, and less than half of the way is Autobahn. It'll take you about two hours one-way. If you don't want to make the journey twice, I'd suggest that I swap out your A1200 board for one that is known-good with Indivision AGA MK3. This will give us all the time required to find the cause, and most of all, it'll give me the freedom to work on the board, maybe send it to Peter.
I'm happy to swap it back after we're finished, but it'll be impossible to start development work while you're here.
