Does it make it into closed loop, at least at times? Fuel trims less than +/- 10%?
i tried it again and it auto ranges. so it is actually stuck between those 2 values. that means it is broken after all. it drives normal, the fuel economy is not horrible and there is not much black stuff in the exhaust.
The car will make a long (400 mile) trip soon.

EDIT: i will check if it goes into closed loop. i will also disconenct the o2 cable and read it with a volt meter.

EDIT 2: the fuel trim is at 0% it never goes into closed loop and the o2 voltage when hot reads 0,4x volt. I order one from aliexpress cus i am cheap basterd
