I had sunroof fitted recently and the fitter told me he had done quite a lot of replacement JLR pano roofs. To do with torsion of the body? Didn’t investigate too much….I checked that out in Google and it seems the fpace and range rovers are prone… might be some useful info there when dealing with Jag.?My XF SPORTBRAKE has a crack in the panoramic roof. The crack is on the inside lamination extending from the centre of the rear edge. The crack is about 350mm long and follows an irregular path. Not really sure what to do. Anyone had the same problem?
