Di Grassi had been operating in eighth status during a safety car duration, which modified into as soon as instigated by Antonio Felix da Costa being eliminated by Porsche driver Andre Lotterer into Turn 1.
As the safety car slowed on how one can da Costa’s DS Techeetah car, di Grassi hit the 50km/h-runt pitlane and tried to give up in the Audi box sooner than rejoining in the lead of the whisk.
Due to leisurely safety car tempo and the short pitlane on the ExCeL Centre, di Grassi climbed seven locations and resumed sooner than lengthy-time leader Stoffel Vandoorne.
He remained in first status on the boulevard as he ran across the pause line after 30 laps but modified into as soon as hit with a sunless flag.
This relegated him to eighth in the provisional results.
On the other hand, di Grassi modified into as soon as now not told by his crew that he had been given a pressure-through penalty for failing to give up fully in the pitbox, having locked up on the slippery indoor floor.
He has now been fully excluded, whereas Audi must pay a suspended €50,000 gorgeous – most productive €5,000 is due straight away – for failing to repeat its driver.
