The German was the dominant force in the opening Formula E race of the season having taken pole and leading the majority of the 37-lap contest at the Autodromo Hermanos Rodriguez circuit.
But Wehrlein, along with reigning champion Jake Dennis, were placed under investigation before the end of the race for a ‘technical infraction’ which was later revealed to be about ‘not respecting the homologated primary throttle pedal map’.
Nearly four hours after being referred to the stewards, officials decided that there would be 'no further action'.
The stewards' document read that 'after intensive investigations the Stewards couldn't find a breach of Regulations' and an 'Alleged Breach of Article 3.2.1'.
