Hamburg - Wolfsburg came from two goals down to earn a 2-2 draw at Bochum while promoted Cologne and Eintracht Frankfurt finished 1-1 in the German Bundesliga on Sunday. Bochum were ahead through Stanislav Sentak in the 12th minute and Christoph Dabrowski with a header five minutes after the break before Wolfsburg came to life.
The visitors immediately got back in the game through Ricardo Costa in the 51st minute and levelled with a well-taken goal from Mahir Saglik in the 69th.
Wolfsburg, who finished fifth last term, have been the Bundesliga's biggest spenders this summer with an outlay of 25 million euros (37 million dollars) on new players.
Felix Magath bought two Italian internationals in Andrea Barzagli and Cristian Zaccardo to strengthen the defence, but the back four was exposed by a simple through ball from Daniel Imhof which enabled Sentak to run clear to give Diego Benaglio in goal no chance.
Wolfsburg's defence was again caught going forward and Mimoun Azaouagh crossed from the left for the unmarked - and offside-looking - Dabrowski to head a second for Bochum in the 50th minute.
The visitors immediately pulled one back through Costa in a scramble in front of goal before Turkish striker Saglik equalized. Wolfsburg pressed for a third and Saglik saw an effort five minutes later cleared off the line by Christian Fuchs.
Cologne and Eintracht Frankfurt earned their first points of the season in a 1-1 draw, but the home side were left to a rue a penalty miss.
Milivoje Novakovic put Cologne ahead in the 33rd minute and Roda Antar had the chance to make it two from the penalty spot six minutes later but his shot hit the inside of the post and rebounded out.
Frankfurt, who were beaten 2-0 at home by Hertha Berlin last week, responded nine minutes from time when Czech striker Martin Fenin headed the equalizer.
After two matches, promoted Hoffenheim top the table as the only team with a maximum six points.
Wolfsburg are one of five teams on four points, along with Schalke, Hertha Berlin, Borussia Dortmund and SV Hamburg.
Defending champions Bayern Munich are still looking for a first win after a 1-1 draw at Dortmund following a 2-2 draw at home to Hamburg.
