Hello, I was a little busy the last few weeks, but today had some time and disassembled the boot. Everything looks fine, don't see anything stuck.
Not sure what else could it be. Might be the issue with the struts, but if it is would the trunk even open if they are bad? Will do a test tomorrow, take the struts out and try closing the trunk, if i feel the resistance even with the struts out, might be an issue somewhere else.
