The 67-year-old has warned Bayern's opponents that his players are in no mood to drop points on their way to a likely Bundesliga title this season.
"All in all, we've been very good since the winter break," Bayern's official site quotes Heynckes as saying. "We're in good shape and in good form.
"We're highly motivated to keep marching on and close in on our biggest target, the German championship."
Bayern would move 18 points clear at the top with victory against Wolfsburg.
