Incredibly on the 17my there's a "time turner" switch (think Hermione Grainger here... no, not that way) just below the bonnet release. I'll be honest I hadn't spotted it before along with the bonnet release for that matter but one press of the switch, which I guess is linked to my BCM and voila, Agnes and her gleaming flanks once more.
Have to say my right arm aches now with all that rubbing but one look of those gleaming flanks and a bit of misguided anthropomorphizing was bound to occur...
