Ferrari has come under increased scrutiny ahead of the Monaco Grand Prix with rival teams requesting the FIA look into a number of concerns with regards its power unit.
Rival engine suppliers Mercedes and Renault have questioned whether Ferrari's energy store meets the technical regulations, with claims the Italian outfit might be employing a second unit within the same housing to provide a power increase above the permitted 120kW limit.
Following the complaints, the FIA says it will more closely monitor Ferrari's power unit this weekend to determine whether there is any evidence of foul play.
Mercedes' boss Toto Wolff is confident the governing body will do its job and ensure every team is working within the rules.
"We have legality topics come up regularly," said Wolff on Thursday. "Some are more controversial but it's the daily business of the FIA to check what the teams do.
"It is the obligation of the teams to comply with the regulations and this is an ongoing process. I have great confidence with whatever issues are coming up, be it on the engine or the chassis, the FIA has been on top of it a lot. And as far as I understand this is a process that’s taking place as we speak and we will see what the outcome is."
Red Bull team boss Christian Horner shared Wolff's opinion, adding: "Obviously there's been some rumours that no doubt you guys [the media] are cottoning onto as well.
"I’m sure that the FIA have all the competence to be able to able to measure, administer and look at the car that’s presented for scrutineering and during a grand prix weekend, and of course it’s the team’s obligation to ensure that that happens. I think the FIA are probably the best people to point that question at."
