Any ideas or solutions

I have a question if anybody has any suggestions or ideas on the issue. I was gonna ask if anyone knows the reason for my 2012 Audi A4 2.0t Quattro is doing a single crank and not starting I just drove home from work fine parked to go into the store and it is doing this now, at the light before getting to the store it had a fluttery idle for a second but now there’s no start and only cranks once and then doesn’t make any other noise
