Help Please EPC?

[Sabri78]

Can someone tell me any info regarding A4/B8 “EPC” warning light ? My Audi drives great usually EXCEPT tonight after getting gas I started driving and the car felt/sound more like a old vw bug all the sudden. I have a 2012 A4/B8 and I’m super bummed because I just bought this car a month ago.
