had my sri 150cdti 22weeks, ive done 7k in that time, and its now on nearly 25k, not sure if my clutch needs attention. it seems to be a bit judderry when taking up the 'bite' also i can feel like a steady vibration through the clutch pedal, but no noise when the clutch pedal is depressed, so hopefully dmf is ok, what do you guys think ? am i covered by warranty ?
