Have a question to all 9-5 Aero drivers. I’ve been having the problem for a long time that when driving with 95 octan fuel the engine starts ringing, a sogenant acceleration ringing. This is best to stop when you have the window open and speed up at a wall or hedge. Since actually shouldn’t be with the T7, and I haven’t heard that in my active Saab screwdriver time I just put the question into the room. Have already tried the DI cash register. With Super Plus, the ringing is gone. Greetings from Passau
