Bayern Munich commenced the match on the back foot after Luca Pfeiffer handed the host a 9th minute lead.
But Kwasi Okyere Wriedt restored parity in the 77th minute with a close range strike.
However, two quick goals from Fabio Kaufmann and Dave Gnaaase condemned the Bavarians to their first defeat of the 2019/20 Bundesliga II campaign.
Wreidt lasted full throttle for the losers while compatriot Leroy Kwadwo played 85 minutes for the victors.
He netted an impressive 26 goals in 36 games for the Bayern youth side last term.
