Sunroof not working

[Twinkle]

I have just bought an 2002 S80 T6 and the sunroof won't work. I have changed the alarm fuse, but nothing. I get the message " Alarm System - service required". I have tried resetting the UEM but to no avail. Pressing the switch does not even produce a noise from the motor. Can anyone help?
cheers

Some help here, the two faults might be linked

Thanks, have checked but not helping with mine. Just love the car though, so may just leave it as is.

It maybe a faulty switch.

the sunroof module is next to the alarm siren in the network sequence, I have seen a few of these. it could be that after replacing the alarm siren it will work ok, if it doesn't then you need a sunroof module as well.
it does not have an actual download, but does require calibrating on vida.
