Augenthaler joined Bayern Munich in 1975 and made his Bundesliga debut for the club in 1977, scoring in a 3-0 win over Borussia Dortmund.

[7][8] In November 1985 Augenthaler committed one of the most infamous fouls in Bundesliga history, injuring Werder Bremen's star player Rudi Völler with a tackle which badly injured Völler and forced him to miss almost the entire remainder of the season.

Between 1983 and 1990, he played 27 times[16] for West Germany, with which he won the World Cup 1990 in Italy in the final against Argentina (1–0).
