What are the reasons why the Mercedes-Benz electric trunk cannot be closed?

There are several reasons why the Mercedes-Benz electric trunk cannot be closed, including a damaged trunk switch, a faulty trunk hydraulic support rod, or the car lock being unable to latch onto the lock catch. Damaged trunk switch: Check if the trunk lock has reset. You can use the metal rod of a screwdriver to simulate the lock catch, pressing it upward horizontally to try to reset it. Faulty trunk hydraulic support rod: If the trunk hydraulic support rod is faulty, it means it has not reset and requires professional repair. Car lock cannot latch onto the lock catch: The gap between the car lock and the lock catch fixed on the bottom door frame may be too small, preventing the car lock from latching onto the lock catch. Adjusting the gap should resolve the issue.
My Mercedes electric trunk won't close, and I've encountered this issue several times. At first, I thought it was due to debris in the slot, but after checking the rear, I found a bag was blocking it, yet it still wouldn't close. Later, I discovered it was a sensor issue—dust clogged after rain, causing the anti-pinch function to activate mistakenly. I tried cleaning the sensor area, which helped somewhat. Another time, the motor made noise but didn't move; it turned out the control module software needed an update. After visiting the 4S shop, the technician diagnosed and fixed it using a computer. Sometimes, dirt on the trunk tracks increases resistance, so I clean and lubricate them monthly. When closing manually, avoid using too much force to prevent faster motor wear. In short, don't delay—small issues can lead to higher repair costs if left unattended. Address them early for peace of mind.
