Just had the windscreen on the i3 replaced. It had been chipped about 9 months ago and Autoglass repaired the site with resin. Then we had 3 tiny chips in the middle of the screen, and the Autoglass man couldn't fix them as they were too small (although affecting the plastic laminate) but was not happy with the original fix. Looking at it again, the cracks were definitely propagating. He said this meant we should get the screen replaced free as an Autoglass guarantee.
I was a little loathe, since I knew of the incident where a whole i3 was written off owing to a botched replacement, but in the end girded my loins and rang for an appointment. Chap in the call centre was very reassuring: they had a screen in stock and they had technicians who do Ferraris and Lambos, so not daunted. Appointment duly made.
Technician arrived with a job sheet saying he had some clips to replace. Er - no - it's the whole screen. He called "control" who said he could go ahead, but he decided it was a 2 person job. So he made a further appointment, came today with his assistant, and 2.5 hours later it's now replaced. It looks as if they've done a good job.
Expensive chip repair for Autoglass, that was.
