The Portuguese driver was stripped of his win in the inaugural Misano E-Prix earlier this month after his Porsche car failed post-race checks.
This was after FIA scrutineers found an ineligible throttle damper setting related to the spring was fitted to the 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 on the car since the start of the Gen3 era as only the addition of new parts was highlighted in the catalogue, not if they had been removed.
Ahead of the Monaco E-Prix this weekend, da Costa believes that such a decision hours after the race is not good for the championship and is difficult to explain to fans when the outcome of the result has changed.
“There is no performance advantage, it’s literally a serial number mistake,” da Costa told Autosport.
“Let’s find another way, just for the good of everyone and everything.
“Obviously on my side, it hurts because I thought it was a well-executed race, I was super cautious, I did the right things at the right times. Won the race from 13th and then your points are gone.
