Wolfsburg sporting director Klaus Allofs told Kicker on Thursday that the club were in discussions with Bendtner, while Danish television station TV2 joined Kicker to later claim the Bundesliga outfit will unveil the forward on Friday at 12:30 local time (10:30 GMT).
TV2 reported Wolfsburg's media relations department had confirmed Bendtner would be presented as a new signing.
The Denmark international's career has been marred by a lack of discipline, including being arrested for drink driving in March 2013, which saw him banned from the Danish national team for six months.
Allofs claimed Wolfsburg would weigh up all factors regarding the striker: "If the chances are greater than the risks, then it could be that we do something.
"In everything we do, we try to proceed diligently. We weigh up what is useful and are still going to consider all options."
Bendtner's agent Thomas Brooks also confirmed negotiations were ongoing when contacted by Sky Sports: "It's correct, we are negotiating with Wolfsburg."
"It is getting difficult. We have looked at the top shelf but it is empty now," Hecking told Kicker.
"Therefore, we must look a little further down."
