The former Gunners forward joined Wolfsburg at the start of the season, but has failed to nail down a regular start.
"I thought I was on the right track, but I do not know what has happened. I am not happy with the first half-season in which I in many ways was disappointed," Bendtner told Kicker.
"I hope we find a better way together going forward, and that I get to play more.
"I signed a contract not for half a year, I signed a long contract with Wolfsburg."
