Thomas Wörle's side stretched their unbeaten run to 37 league games in the process.
Melanie Behringer opened the scoring with a stunning strike from long range, before Tessa Wullaert leveled in the 90th minute.
The hosts could find themselves outside of the Champions League places tomorrow, should 1. FFC Frankfurt get the better of Turbine Potsdam.
Wolfsburg on top in the first half
The game, from the start, had the look and feel of a league deciding clash. Despite the gap between the sides, the tension was palpable. If Bayern won they would stretch their lead to an almost insurmountable level, but Wolfsburg were keen to close the gap to nine - keeping alive any faint hopes of a late challenge for the title.
Therefore, it was no real surprise to see both teams playing with caution in their game early on. It was a struggle for Wolfsburg to convert their possession into chances and even when they had a promising position to cross, Tinja-Riikka Korpela was on her toes to claim the ball. Bayern, on the other hand, were struggling to make any moves forward.
The first real shot of the game came midway through the half. Caroline Graham Hansen lined up a free-kick on the right and, in what seemed like a cross, slammed a low, hard cross at goal. No-one got a touch on the ball but the swerve brought the effort onto the inside of the post, before bouncing back out.
Frustration was growing for both sides and that finally came out in a series of rash challenges. Lena Goessling required treatment after Vivianne Mediema's stray arm caught her in the face, and Zsanett Jakabfi went down under a heavy challenge from two Bayern players. Therefore when Hansen was booked for a late challenge on Caroline Abbé, the home fans felt hard done by.
Jakabfi was soon up again and flying down the left wing, before rounding two players and whipping a promising ball into the near post. Unfortunately for the wing-back, Korpela was able to intervene just before Hansen got a crucial touch at the near post. Despite the best efforts of the hosts, the game went into the break all-square.
Behringer fires Bayern ahead, Wullaert saves a point
Bayern began the second half with more attacking intent than they had shown in the entire first half. Lisa Evans had a hopeful penalty appeal turned down on Nilla Fischer, while Sara Däbritz and Nora Holstad Berge both had early opportunities to give their side the lead.
The visitors' pressure did eventually pay off, shocking the AOK Stadion into near silence. After a good run from Melanie Leupolz, name-sake Behringer took on the ball and struck a stunning 30-yard drive that arrowed into the bottom corner. Almuth Schult was powerless to prevent it going in, and suddenly the game had flipped on its head.
After that, it became much like the opening stages of the first half. The introduction of Isabel Kerschowski had little effect on the game as Bayern, essentially, shut up shop. The dribbling of Däbritz helped run down the clock, and the resulting free-kicks only aided their charge.
There was one final chance in the game for Bayern as a deep free-kick was thrown into the box by Behringer and met by Holstad. The ball looked destined for the back of the net but a stunning stop from Schult managed to flick the header onto the bar.
That intervention proved to be the turning point, as Wolfsburg grabbed a last-minute equaliser. Some neat play around the box allowed Hansen to burst past her defender and cross brilliantly to substitute Tessa Wullaert, who was able to slide the ball home unmarked. A second would not come, however, as Bayern maintained their lead at the top.
