"Hey guys, I'm at my wit's end here. Got my 2020 Audi A4 a few months ago and it's been a dream ride so far, but lately, I've noticed my fuel efficiency has taken a serious hit. I'm seeing an average of 15mpg in the city and 25mpg on the highway when I know it should be better, can anyone else with an A4 vouch for similar issues or point me in the right direction for a solution?"
