Lewis Hamilton missed out on a world title in his final season with Red Bull.
Lewis Hamilton will not make a decision on his Formula 1 future until he sees the results of the inquiry into the Abu Dhabi Grand Prix.
Wolff said that Hamilton is "disillusioned" with F1, as a result of last year's title-deciding race.
Hamilton lost the title to Verstappen because the race director did not apply the rules correctly during a late safety-car period.
Hamilton lost trust in the governing body as a result.
When asked about the situation surrounding Hamilton's future, Mercedes declined.
The team and Hamilton are waiting to see what action the FIA takes to address the issues raised by the Abu Dhabi race.
The seven-time champion's confidence is at stake, as is the reputation of the sport, as the FIA launched an inquiry into the events at the Abu Dhabi race.
The new president said he has been in touch with Hamilton since he was elected.
"I don't think he's ready to respond right now," Ben said last week. We don't blame him. I understand his position.
The final race of the season has caused some senior F1 insiders to worry that the governing body has not fully grasped the threat to its credibility.
It has been a month since the race. When asked about the timing of the inquiry's findings or what matters it will seek to address, the FIA said it was not yet ready to answer.
The events of Abu Dhabitarnished the image of F1 but also generated significant misunderstanding and reactions from teams, drivers and fans, according to a statement from the FIA.
The inquiry will be done in time for any identified meaningful feedback and conclusions to be made before the beginning of the season in the year 2022.
The first of two pre-season tests starts on February 23, while the opening race is in March.
The future of Masi is in doubt because of his handling of the race, which came at the end of a season in which there were repeated concerns among teams and drivers over the consistency of application of the rules.
A senior source told the radio station that Mercedes had dropped their appeal after agreeing to a deal with the world governing body.
The deal was said to be that Masi and Tombazis would no longer be in their positions in the year 2022.
Mercedes dropped their appeal after receiving assurances that the issue would be treated seriously and appropriate action would be taken by the FIA.
Wolff said last month that Mercedes would hold the FIA to account.
He didn't say how he intended to do that, but he said he had faith in the teams and drivers to create a more robust decision-making process.
Several senior figures told the BBC Sport that they don't see how Masi can retain his position as race director, but that the FIA is in a difficult position because there is no obvious replacement.
The championship was decided in the last race of the season.
What is Hamilton's contractual situation?
Hamilton signed a new two-year contract with Mercedes last year, which is thought to keep him at the team until at least the end of the next season.
George Russell, one of the leading lights of the new generation of drivers, has been recruited by Mercedes to be the seven-time champion's team-mate.
The most likely outcome is that the FIA will take significant action and that Hamilton will return in 2022.
It is not clear who Mercedes would recruit to replace Hamilton if he decided to step away from F1.
It is likely that Mercedes will have to find a new driver to replace their current one, as they did with Valtteri Bottas when they bought him out of Williams.
What happened in Abu Dhabi to upset Hamilton?
The safety car was sent out when Nicholas Latifi crashed his Williams at the end of the race, and Hamilton was on the verge of winning his eighth world drivers' title.
Mercedes felt they could not do the same thing with Hamilton because it would have meant the Briton losing the lead with no certainty the race would restart.
Masi failed to apply the rules correctly.
Normal protocol is to allow all the cars in the field to un-lap themselves so that they don't interfere with the racing on the restart or leave all in place.
Masi allowed the five cars between Hamilton and Verstappen to un-lap themselves, so they were not in the way, but left all the others in place, including the two cars between Verstappen and third-place.
Masi ignored a rule that requires the race to restart at the end of the following lap after the lapped cars have been removed.
There needs to be clarity going forward.
Verstappen used the extra grip of his fresh tyres to pass Hamilton and win the race and take his first world title.
An initial appeal by Mercedes against the results of the race was rejected by the stewards. The team gave notice of their intention to appeal but withdrew it after three days of talks.
Wolff accused Masi of leaving Lewis "like a sitting duck" and said that robbing him in the last lap of the race is unacceptable.
He said that there is a bigger problem for the FIA to solve than just finding a new race director.
Wolff said that the whole system of decision-making needs to be improved. The race director is under a lot of pressure and some of it is due to our own fault.
Team principals will no longer be allowed to contact the race director during a grand prix, as a result of Abu Dhabi.
Wolff and Red Bull's Christian Horner have been lobbying for actions that favour their teams in the race, which has become normal practice in recent seasons.
