ugh.... when I had my P38, the sunroof had an issue and wouldn't close right. I normally do all my own repairs, but to this day, this is one repair that I was more than happy that I took it to the dealer and let them figure it out. LR ended up buying an entire scrap P38 to scavenge parts from (or so they told me). They fought the thing for a long week. I know, that's not helpful to your question, sorry, but it made me think of this one.
