Mario Mandzukic and Ashkan Dejagah scored two goals apiece as Wolfsburg beat Cologne 4-1 to secure a crucial victory in their fight for Bundesliga survival.
Mandzukic put the 16th-placed Wolves in the ascendancy with goals after 14 and 39 minutes at the Volkswagen Arena.
Sebastian Freis pulled one back for the visitors five minutes before the break, but substitute Dejagah netted twice in the second half to seal the three points.
After previously collecting just one win in their last 11 matches - and one in their last ten at home - this triumph moved Wolfsburg two points behind Eintracht Frankfurt in the final position of safety.
Mainz held Nurnberg to a goalless draw to stay two points clear of their opponents in the race for Europa League qualification.
Mainz had the better of the chances with Elkin Soto and Sami Allagui going close either side of half-time, while Mehmet Ekici hit the post for Nurnberg, but neither side could make the breakthrough.
The draw kept Mainz in fifth place with three games of the season remaining.
