Avant Automatic boot not quite closing

Slightly long story. My avant boot lid wasn’t going up high enough, resulting in a banged head. Upon investigation I found the wrong gas struts had been installed, they were too short and had the wrong force.
I ordered the correct ones and installed them. Simple enough.
Now the boot closes but I need to give it a little push when the boot reaches the bottom for the electronic closer to grab it. It needs to either go a little further down or drop with a bit more force.

Anyone got any ideas? Is there any way to adjust it?

thanks!

Ok, that’s great thanks. I’ll have a look.

It seems to have done the job. It wasn’t quite as you described, you have to turn the slim wide plastic nut beneath the rubber bung. I used an adjustable spinner and mole grips (not ideal). Photo attached.

I wouldn’t have spotted it without your mention @Duck A4 so thanks again!
