Hello everyone! I drive A4 Petrol 35 TFSI Sport Automatic. Since 2025, I noticed when I drive it vibrates at speed of 60mph and after that i think its ok. This is been going on for a year. it has not gone worse or bad and vibrates and then i think it disappears. What could it be causing this? Engine is fine no noise and geabox shift smoothly. Any advice I would appreciate it thank you.
