hi all, I have 2 issues with my 2006 A3 2.0 tdi SE, 6 speed manual 1. The trip computer is blank. The only light appears is when a door is open and a small dim red light appears showing the door is open, at the centre of the screen. I also do not have the reset button on the bottom of the wiper stalk. 2. There is vibration SOMETIMES when i'm travelling at round 70-80mph on 6th gear on the motorway. although I am not entirely sure if it's only if i'm on 6th gear. Have some vibration at stand still, on idle too. What gives?
