Mark Webber will have a five-place grid penalty for the Belgian Grand Prix because of a gearbox change.
The Red Bull driver, who is Fernando Alonso's closest challenger in the Formula 1 world championship, finished the last race in Hungary so the gearbox change means he is in breach of the regulations.
Webber suffered a similar penalty at the German GP for having a new unit fitted to his car.
A statement issued by the FIA confirmed that the change, which will be made before the start of practice three on Saturday, will lead to a five-place penalty.
"The above driver [Webber] did finish the last race in Budapest and this gearbox change was before the five consecutive events expired," it said.
Webber and team-mate Sebastian Vettel have suffered their share of reliability problems this year - although the Australian has not retired from a race.
Speaking about the team's reliability performance this year, Webber said: "Seb lost a lot of points in Valencia. I've lost a lot of points a few times too, so we've had a bit of friendly fire within our own operation, but generally we always grab something at the end. Generally that's down to the quality of the team."
