Heard a bad scraping noise from driver's side wheel this evening. Assumed it was a stone stuck between the disc and dust shield. One point to note...the Jazz has thick shields which are very nice quality!
Anyway, with full lock on I saw and found nothing. Problem persisted so checked on opposite lock and found some large twigs had lodged themselves into a gap toward the rear of the wheel arch cover (sitting over the sub-frame).
Not easy to pull out and quite sharp, so I have a nasty feeing they've killed the left CV boot (as they were pressing up against it). Unfortunately too dark and cold to make a proper inspection, but it does raise the point why Honda decided not to fit an underbody engine cover to the Crosstar.
I certainly didn't roll over the twigs and their final resting place leads me to think an undertray would have likely deflected them.
I'll find out in the morning. Fingers crossed, it's not torn or leaking!!
