Intrigued as to whether mine is broken or not I've done some googling and testing (I'm sure being laughed at by the neighbours as I stand opening various doors and staring at them in the drive!!).
It seems all the golfs have something called "stepless door angling" which means it holds at any angle.
Having tested, mine has a definite rest point at about 9 inches open where the door sort of falls to, it then has another one at wide open where if the door is within a couple of inches, it will go into that position if let go.
And for the rest of the travel, it does indeed have a bit of resistance and will hold to a degree.
So not broken, which I'm glad about, but doesn't give me a great degree of comfort, I guess with many years of a secondary stop, I expect it to be there so have been thinking there's no hold in the middle ground when in fact there is some.
Now I'm aware of it, I'll be more conscious of it in the real world and might appreciate it more.
