I apologize! Niklas, you're absolutely right! I found it on dbautozug.de now that I took a closer look... I didn't see Hamburg on that list before. I'm sorry about the confusion I may have caused. The Deutsche Bahn has discontinued all southbound DB Autozug trains from Munich, however the northbound ones are still going (thus, when going from Munich to Narbonne one has to drive to Duesseldorf first). I got those two things confused, so again: I'm sorry.
Yes, there is a DB Autozug going from Hamburg-Altona to Munich-East and it looks like there are still some spots available.
