The German had finished third in the race, which took place on a virtual version of Berlin's Tempelhof Airport street circuit, when second-place finisher Stoffel Vandoorne called him out on Twitch for not driving the vehicle himself.
Abt later added that it was never his intention to "get a result and keep quiet about it later on just to make me look better".
As public criticism of Abt's actions mounted on social media, Dutch driver Nicky Catsburg - who competes in a range of events for Corvette Racing, BMW and Hyundai teams - said in an interview that what had happened "has nearly made me afraid of sim (simulated) racing".
In Berlin, the No. 66 Audi had its best showing by-far since the Race at Home Challenge kicked off, qualifying second and leading for a spell ahead of Mercedes' Stoffel Vandoorne and eventual victor Oliver Rowland.
'We won't be racing together anymore'"Today I was informed in a conversation with Audi that our ways will split from now on", Abt said (11:43).
Audi said in an earlier statement that "integrity, transparency and consistent compliance with applicable rules" were top priorities.
Instagram: daniel_abt Abt is a Formula E driver for Audi. In the post-race interviews, Vandoorne not-so-subtly queried, "To be honest, I'm questioning if it was really Daniel [Abt] in the vehicle", in the post-race interviews.
"When I drove this race on Saturday, the other drivers reacted to it of course and realised that there was something odd". Worse still, Audi has now distanced himself from the Formula E driver and so he loses everything in a short time.
Formula E investigated and announced on Sunday that Abt had been "disqualified from the race for sporting misconduct". It's a pain which I have never felt in this way in my life. He has now been banned from the tournament and he has been suspended by his race team Audi.
He said the idea came from a discussion with sim drivers that it would be fun to pit a gamer against real drivers in the event to show what he could do against professional drivers. "It's a simulation which does not have anything in common with real racing, which is what I'm normally doing", he said. "We wanted to document it and create a amusing story for the fans with it".
"The online Formula E race is based on rFactor 2, which is a game".
