Hi, I have a 2008 2.0 sport. having problems with my roof operation, decided to try the sensor first as I can hear the motor working like a good un, but the roof wont come up. goes down fine but I have to pull the red handle in the boot to get it up. red light on roof opening switch flashing, but the parcel shelf if fully down. fingers crossed its the sensor, has anyone got the part number as I cant find it, thanks to all previous posts on this forum for getting me this far.
