C70 Tailgate handle microswitch removal
 

I'm trying to replace the microswitch on the tailgate as the sensor for the boot unlock is not working. While removing the screws for this and the licence plate lights loosens the microswitch i cant work out how to get into this part of the tailgate to remove. I also canot find anything on the internet ,youtube etc to help with this. Can anyone please help as i dont know if this is held in with simple clips or i need to uncrew somewhere from behind. Many thanks . Tony
