Goals from Maximilian Eggestein and Kingsley Coman ensured the spoils were shared at the Allianz Arena on Saturday.
Bayern Munich dropped points for just the second time this season as they were held to a 1-1 draw by Werder Bremen on Saturday.
Maximilian Eggestein's well-worked goal gave the visitors a deserved lead late in the first half before the champions struck back through Kingsley Coman after the hour.
But they were unable to build on their equaliser as a dogged performance from Florian Kohfeldt's men earned a deserved share of the spoils.
Werder travelled to the Allianz Arena having avoided defeat in their previous four outings, though each of those ended in draws.
