According to your video on my Karcher K4 I should simply "plug-in" the detergent bottle. I have done that but it doesn't seem to release the detergent. Do I need to force the bottle hard or pierce the nozzle in some way?

You have to remove the rubber bung on the top, this allows the fluid to get out via the valve.

We do not have any information other than that shown in Karchers video at https://www.youtube.com/watch?v=gpIeH_4Y0Ns . It does mention that on many models you may turn to low pressure to dispense the detergent.
