Hi to all the technical wizards out there. I've just encountered a strange issue with my GLC's boot opening and closing. The boot will open and then immediately close. I've tried opening it via the door, boot lid and key and in all instances, the boot will immediately close after two beeps. There is nothing above the car that would impede it's opening. I've also tried opening away from the wall and with the ignition on. All with the same issue. I've tried holding the lid open at the top to 'reset' the position, but it will just auto close each time. Here's a video demonstrating the issue: This is a new issue and not something I've experienced before. Any advice appreciated. Thanks in advance.
