Hi all. I've just bought a Discovery 2 TD5 auto on a 51 plate. I've noticed the mode button by the gear selector doesn't do anything. There are no "S" or "M" lights on the dash when I switch on the ignition. Does this mean my car doesn't have sports/manual mode (was it an optional extra?) or does it mean there must be a loose connection/fuse etc? Any advice appreciated, I'm new here!!
