Goals from Simon Kjaer and Edin Dzeko gave Wolfsburg their first win in four matches.
Diego may not have been at his brilliant best in recent games but his corner led to an early opener for Wolfsburg in the sixth minute. Simon Kjaer met the ball with a bullet header, which beat Sven Ulreich before bouncing off the underside of the crossbar and over the line. Although Edin Dzeko then followed up to make sure, there was to be no denying the Dane his first Wolfsburg goal.
The normally clinical Bosnian spurned an excellent opportunity to double the lead on fifteen minutes when he latched on to a trademark Kjaer ball forward with too much nonchalance and could only hook the ball into Ulreich's arms.
Midway through the first-half, Cristian Molinaro cleared Andrea Barzagli's shot off the line as Stuttgart came under serious pressure. Two minutes later, the post came to die Schwaben's rescue when Grafite capitalized on a Serdar Tasci mistake and from the resulting corner, Molinaro made another heroic block as the Brazilian striker was again denied.
Jens Keller's men showed some spirit and Martin Harnik had a chance on the half-hour when his 25-yarder was stopped by Marwin Hitz. Gentner, who along with Harnik was outperforming his team-mates, then chipped the ball on to the top of the net on the stroke of half-time.
The home side should have moved further ahead but Ashkan Dejagah skied a glorious chance from twelve yards out on 52 minutes. Stuttgart again showed some fight on the hour mark when Hitz was forced to beat away Christian Traesch's long-range effort before Harnik again shot straight at Wolfsburg's young Swiss 'keeper some minutes later.
The hosts then sealed all three points with a quarter-hour to play, again from a Diego corner. This time Dzeko was awarded the goal thanks to his glancing header from close range as the captain ensured there was to be no repeat of the horror home defeats to Mainz and Bayer Leverkusen.
Stuttgart have dropped down to sixteenth place. They host Werder Bremen next weekend in a north versus south clash. Wolfsburg remain in thirteenth spot and next week travel south to face Eintracht Frankfurt.
