BMW F20 automatic tailgate conversion - using flat compression springs from bearingboys.co.uk

Opening of the rear hatch/tailgate of a F20 BMW conversion
Sorry about no explanation earlier on. I inserted the video for private use to show my dealer, that this can be done, and that's why I didn't give any description in the video...
Two flat springs on each strut. That is all that was required. When pressing the button, the springs push the tailgate away slightly and the gas struts do the rest of the job by themselves.
