I've removed the headliner and sunroof to recover both but reinstated the sunroof cartridge only so I can still drive about. I don't think it leaked before, nothing obvious anyway but there was some staining. Anywhoo, we've had persistent rain overnight after a long dry spell and the wife was non to pleased to have water dripping on her lap at 5.30 this morning lol!
Back home after dropping her off and using a torch I can see water between the foam seal and the internal surface of the roof skin. The seal isn't sitting correctly in relation to the rest of it so I guess that's the issue.
Thinking about it further , im not sure water should actually get there unless there was a real heavy downpour that the drains couldn't cope with? All drains were cleared, they weren't blocked anyway tbf and the drain pipes reattached tightly to the cassette stubs, the waters getting in above the stub , nearside front, anyway , passed this foam seal. I assumed this seal was just for draught proofing but now I don't it must be a secondary water seal.
Bit of a bummer because it's heavy and it's got to come out again. Anybody know the part number for this foam seal ? I can't find it listed.
