The Bavarians last tasted defeat against Bayer Leverkusen a year ago and their win against Augsburg on Saturday saw them beat Hamburg's long-standing record
The Bavarians stormed to the German title last term, losing just one game on the way, a 2-1 home reverse to Bayer Leverkusen last November.
They finished a total of 25 points ahead of nearest rivals Borussia Dortmund and have made a flying start to the current season, having won all but two of their matches, draws with B04 and Freiburg.
Bayern have survived some the Bundesliga's most daunting away days during their extraordinary 37-match unbeaten run, including trips to Dortmund, Leverkusen and Schalke.
Hamburg set their original record between matchday 17 of the 1981-82 season and matchday 18 of the 1983-84 season, claiming two titles during the course of their run.
