McLaren have dropped their appeal against their loss of constructors' points from the Hungarian Grand Prix.
McLaren were stripped of their points after an incident in Hungary
The team were stripped of their points after Fernando Alonso blocked Lewis Hamilton in qualifying.
They have since been thrown out of this year's constructors' championship after being found guilty of an intention to benefit from Ferrari technical secrets.
But McLaren had considered continuing the Hungary appeal because it may have led to a reduction in the £49.2m fine.
That fine, part of the punishment handed down by the sport's governing body in the spy scandal, will be reduced by the amount of prize money McLaren have earned for the points they scored up to the Italian Grand Prix earlier this month.
The higher a team finishes in the constructors' championship, the more money they earn.
So it was mathematically possible, if the Hungary points were included, that McLaren might have had more points by Monza than Ferrari will score by the end of the year.
And that could have saved them several million pounds.
But a statement from the FIA said McLaren had notified it of their "wish to withdraw their appeal".
McLaren have yet to say whether they intend to appeal against the fine and ban for possessing confidential Ferrari documents.
