Da Costa claimed his first win of the season on Formula E’s inaugural visit to the Misano World Circuit Marco Simoncelli last weekend.
The Portuguese driver scored his first victory since the Cape Town E-Prix last season having passed Nissan's Oliver Rowland three laps from the end of a chaotic race which included 19 changes for the lead across 28 laps.

But several hours after the race, da Costa was stripped of his victory after scrutineers found an ineligible throttle damper setting related to the spring was fitted to his car.
The part in question had been previously used on the Gen2 machines but its inclusion in the “GEN3 Spark Catalogue” was removed when the new car was introduced for the 2022-23 season.
Porsche admitted that the spring had been used since the start of the Gen3 era as only the addition of new parts were highlighted in the catalogue, not if they had been removed.
Immediately following the disqualification, Porsche lodged an intent to appeal giving the German manufacturer 96 hours to decided whether to pursue the matter.
On Wednesday just before the deadline, a statement read: "We can confirm that Porsche lodged an appeal against the decision #31 by the Stewards relating to the 2024 FIA Formula E Misano E-Prix, 13 April 2024."
