Default S60 II T6 3.0T 2012 strange AWD symptoms

Hello everyone,
Fourth generation Haldex. Can you give me some advice, because unfortunately I've run out of ideas.
The drive does not turn on, it only happens in the morning or after a long standstill. When I start the car when cold, I try to move it and I see that the rear is not working, but after driving a few kilometers or after some time, the drive turns on and then it works perfectly, without any problems. Sometimes I have to hold the brake and gas at the same time several times and try to move, and after some time Haldex starts working.
The pump was regenerated, the oil was replaced, the filter was also replaced, the n373 pressure regulation valve was also replaced, there were no errors in the DEM. Do you have any other ideas?
Thank you very much for your interest in the topic.
