I am interested because I am traveling to Germany soon and have a factory tour reserved. My German is decent so am interested in a tech manual both for practical use and as a souvenir.
When Porsche updated their PIWIS factory diagnostic system in 2003-4, they moved from printed manuals to an entirely online system called TSI. Because the PIWIS system went from a free-standing unit to a 100% networked system (to prevent cloning or theft of their intellectual property) that was lease only, they included the TSI part of the $20,000 (first year) lease cost.
