Hello everyone, new member here seaking help of some fellow Audi owners. I have a 2018 rs3 ds1 stage 2 flexfuel with upgraded injectors. So about a week ago my car just randomly decided it didn’t want to turn on I figured since it was cold and it was on e85 it was normal. It got worse, the car just randomly would die on me, struggled turning on would randomly bog when hitting small pot holes and eventually I started hearing a high pitched whine from the fuel rail/injectors. With that being said I switched back to 91 removed the big injectors (they were dirty) and put the stock ones back on (no more struggling to turn on or bogging etc) but the wine is still there. It’s not all the time you can hear it but the car is running a lot better with the stock injectors. I have a video of it but I can’t seem to attach it here
