Mercedes E320 what to do when the trunk doesn't open

One day my 1999 Mercedes E 320 trunk wouldn't open. I couldn't find a way to open it on the internet so I decided to make this video. I hope this is helpful.
By switching the trunk actuation air hose with the door lock hoses I was able to open my trunk with no problems.
Keep in mind my door locks work as does my gas tank access.
