Hi I've just got my S3, hope I'm not already in trouble...
had a problem selecting reverse today. It was a bit difficult to get it in, (ooeer) push down and move it across, but it just wouldn't go, no grinding though. Give it a wiggle and it would pop in and be fine.
But then I tried to reverse later on and it just would not get in gear, no matter what I tried I couldn't get reverse. I got worried because if I went forwards I'd be in someone's front room, was 1/3 of the way through a three point turn!
I turned the engine off, restarted it, and it went straight into gear. huhh??? It 's like the gearbox is made by Microsoft... restart and it's fine.
