I have an issue with the lazy suspension.


When the standard rising procedure is executed (opening/unlocking doors), I've noticed that it takes much longer for the car to rise to its standard riding height in the last few days.
The pump is working, but nothing happens for about 15-20 seconds and then goes up at the usual pace. After that, it is possible to get to the highest position without any issues.
Before, it would go up almost immediately after the pump started working.
There is enough fluid and I've gone through the bleeding procedure (to double check), so there should be no air pockets.
I see no leaks and the fluid level is correct and not moving a bit.
I don't know where else to look because everything seems to be ok and nothing has been done to the suspension lately.
