Hi everyone, just joined and would like to ask a question regarding an issue my Audi has recently developed. I have an A4 3.0 tdi B7 auto and during gradual acceleration from around 20-30mph there is heavy juddering from the engine. I'm assuming it could be a driveshaft or gearbox issue. It doesn't do it when I accelerate hard but only during gentle acceleration or just cruising around that speed. I haven't driven the car outside of town yet to see if the problem continues at higher speed and rpm. Any suggestions would be very welcome.
