Ayoop folks, we took her out for a run (breakdown services unknowingly on standby!) and put her through her paces on comfort setting, so roundabouts, fast exits from junctions etc and all seems good......I kinda wonder what's going to sulk next, but I'll cross that bridge when I get to it. In the meantime, the fuel gauge isn't working and I sometimes can get it to work by folding down the offside rear passenger seat, or placing something heavy on the seat cushion. I wonder if this means a wiring fault as opposed to a failed(ing) sender unit. As I rarely use the performance, 600 miles between refills is what I go with, but the range data would be nice to have again.....thanks again everyone.
