trunk stuck (w210)
 

On my 97 E320, the trunk does not pop open when the indoor electric button is pressed. All you hear is a pfissst noise but the trunk does not pop open. I think it is the vacuum plug but I'm not sure. Please reply with help.

if you can open the trunk manually check the vacuum diaphram and the vacuum lines. i think these are located right behind the lock behing a cover.
