having same issue on mk3 vr6 - but the sunroof works fine for tilt, but it won't slide back - when I try the switch it clicks and go back a little and stops - I try the switch again it goes back a little and then stops - I've tried the manual usage with the allen key works fine all the way back... I've cleaned and lubricated all parts - still not working? What do you think - is this switch or motor gone?
