Got ya message with your details last night, thanks for that as it's so much easier to check with the exact info, right where do i start ?
first off a full list of PR spec codes for your car si we can see the menu Seat made it from, but note the 3FE code for later
As the above list in reality means bugger all as it is I've printed off the full list of the specs so I/we can see what to check and other's can scan through for other stuff if needed
Again 3FE is listed lower down (pg3) = Electric slide/tilt sunroof with sun screen/sunblind
Couldn't say either way in the beginning what is supposed to be fitted and is so using Etos parts system filters i can check the exact parts as required for that particular vehicle.
As you can see below it lists the same spec as the codes matching (3FE) and describes the roof exactly as i would expect.
But this was printed via the filter so it narrows it down through the filter to keep a list short and printing optimum etc etc so i have also added a screenshot of the actual page as it reveals something interesting
As you can see the 3FE code shown as expected but in the grayed out area there is 2 options listing 3FR - for 'solar' sliding roof

Damn !!!
According to the parts system your Car is listed as being specced for a standard sunroof 'NOT' a solar type one
Now before you blow up a
dealers and declare war on Seat of bear in mind this is all info as listed by Seat and can be wrong (rarely i'll confess though) but it would be worthwhile comparing the codes actually on your car's
sticker and as a double check with another owner that does have the option.
Computer's and robot's can be fallible as much as humans sadly.
Hopefully it's merely an admin error somewhere along the line but equally if not i hope the info helps your cause.
