Kevin Danso's equaliser prevented Borussia Dortmund from continuing their revival with a fourth consecutive Bundesliga win, Augsburg claiming a 1-1 draw at Signal Iduna Park on Monday.
Peter Stoger is yet to taste defeat in nine games since being appointed as the replacement for Peter Bosz in mid-December, but the coach will feel his side should have won this game.
A fine team move saw Dortmund take an early lead, Marco Reus on target for the second Bundesliga match in a row, the Germany international tucking home a close-range rebound.
Augsburg had chances to take a draw from a quiet, sparsely-populated Signal Iduna Park, with Dortmund fans protesting against their first Monday match in 28 years.
And in the closing stages Augsburg earned a hard-fought point, Danso thumping in after Roman Burki parried his header to snatch a result for his side.
Dortmund sit a point clear of third-placed Schalke, but with a massive 19 points to make up on Bundesliga leaders Bayern Munich there is little hope of BVB reviving a long-over title race.
Although Augsburg are yet to win away in 2018 they started on top, Michael Gregoritsch recording the first shot on target, although Burki made a comfortable save.
But after 15 minutes Dortmund were in front, scoring from their first meaningful attack.
Reus won the ball in his own half, launching a rapid break through Julian Weigl, and with Martin Hinteregger only able to block Andre Schurrle's low cross Reus was on hand to lift a clever finish over the prone defender and into the roof of the net.
Gregoritsch cleared the crossbar with a free-kick and Raphael Framberger fired at Burki after 25 minutes as Augsburg hunted a leveller.
Jonathan Schmid tested the BVB goalkeeper with another set-piece shortly before half-time, Burki unconvincingly getting down to his right to turn the dipping effort around the post.
Augsburg continued to threaten after the interval, Schmid and Hinteregger both missing the target with decent headed chances.
Dortmund substitute Mahmoud Dahoud fired off-target moments after his introduction and Schurrle almost made the points safe, his 18-yard drive fading wide with Marwin Hitz beaten.
Augsburg had scored in eight successive games against Dortmund and the visitors scored a deserved equaliser after 72 minutes.
Danso lost marker Sokratis Papastathopoulos and, although Burki saved his header from a right-wing Schmid corner, the defender smashed in the rebound to set up a grandstand finish.
But when the best chance to win the game fell to Dortmund, Michy Batshuayi hammered a shot over the crossbar after taking the ball away from captain Marcel Schmelzer.
