Hi all
Has anyone else noticed when you open the boot it feels like its under pressure? My boot might need adjusting!

All joking aside...as cars become better sealed for aerodynamics, there is usually a internal pressure relief valve in most modern cars. The Mk 1 Citroen C4 certainly had one as did my old Abarth 500. Usually down in the bowels of the boot, the valve regulates pressure inside to out....and probably prevents blowing your ear drums when you slam the door shut!
