The Mercedes F1 team has made an adjustment to its front wing following talks with the FIA after the Chinese Grand Prix.
Mercedes walked away from the Shanghai event in high spirits after Kimi Antonelli secured his first race win, while George Russell’s second place secured maximum points.
However, its front wing caught the attention of rivals after a strange pattern was detected.
Replays showed that through the active aero system, the wing ran flat as normal along the straights.
However, as it then went into corner mode, it briefly held an angle at a halfway point under braking before moving to the acceptable level.
It prompted concern from some rivals as the technical regulations outline that a transition time between the two modes must take no longer than 0.4 seconds.
The FIA engaged in talks with Mercedes to get to the bottom of the matter.
Mercedes has since made an adjustment to the component as it believes the issue in China was reliability-related, rather than a deliberate performance enhancer.
The team is hopeful the fix will rectify the problem and eliminate any further scrutiny from rival teams.
It is not the first time the Brackley-based squad has faced queries this year, as much of the pre-season noise surrounding the team related to the compression ratio advantage of its power unit.
The FIA previously ruled that Mercedes must adjust its engine to comply with technical checks from June 1.
The Silver Arrows enter the Japanese Grand Prix this weekend hoping to take their third successive win and continue a perfect start to the new season.
