Wolfsburg survived a late rally by Borussia Monchengladbach to keep on the coat-tails of the Bundesliga's early pace-setters.
Alexander Madlung scored the opening goal in first-half injury time for the reigning champions and Christian Gentner made it 2-0 two minutes into second-half injury time. American midfielder Michael Bradley pulled a goal back for the visitors a minute later, but the Wolves hung on.
The victory gives Armin Veh's side 16 points and leaves them fifth in the table, five points behind leaders Bayer Leverkusen and Hamburg.
Monchengladbach remain second from bottom with seven points after losing their fifth straight game and sixth of the last seven contests.
Borussia Dortmund jumped two places with a 2-0 victory in the Ruhr derby over Bochum. Lucas Barrios and Neven Subotic scored the goals for Jurgen Klopp's side as they inflicted a first defeat on Bochum's caretaker coach Frank Heinemann.
Diego Klimowicz hit the post for Bochum, but they were outplayed by their hosts.
