No idea Jon.
I remember when Jays one went, there had been a number of cracked windscreens posted here, almost all on 4/4 Sport, a number of which had occurred overnight while cars were parked up. Relatively fewer reported on other models, on here (and MogTalk). Possibility other models were under-reported, of course.
There was a conclusion as to likely cause posted here in a thread about them, but it was a good few years ago. Not heard/seen anything about windscreen cracks for a few years, so assumed (dangerous things assumptions!) that the problem had been resolved.
