Hi guys, I've got a retro fit automatic boot kid opening kit for BMW 5 series E39. When you press the boot lid button on the key the boot lid opens. It works with 2 springs going over the struts. This is not a electronic mod but a simple mod with springs and washer. It's opens all the way buyt tryout have to manually close the boot. Kit includes: 2x springs 6x washers 2x heat wrap material to cover springs 1x instructions £16 includes P&P PM me if interested.
