Stolen Boot Release Sensor? VW Passat.

Thanks Colm, I was pretty sure that there wasn't a hole there before, but ya, what you say does make sense. I was hoping someone might the same sensor on their car and could confirm if there should be a sensor there. I had spotted those drawings you posted, it looks like item 3 is a cover to access a sensor or controller? If so i couldn't see that on my car, which is why i taught in was in the center. My girlfriends dad is a retired cop and mentioned that apparently access through the bumper (Whats happening with Land Rover i think?) and could have been an attempt to get into the car? So ya, not 100% sure of anything at the moment 🤷‍♂️ . I know the same time i noticed the sensor not working i started to get an exhaust smell in the car as well at times, which i taught at the time might have been an exhaust leak at the engine bay, but when i saw the hole in the bumper that maybe some fumes were getting in through there into the boot (the car is an estate so open to the car). Could be a coincidence both happening at the same time.
