I understand this regulation doesn't apply to German airspace, but to German-registered aircraft. So you can fly a UK-registered aircraft IFR in Germany without an autopilot, but you can't fly a German-registered aircraft IFR in the UK without one.
The regulations are in the Betriebsordnung für Luftfahrtgerät (LuftBO), which is published in German.
