BMW E65 730D - lack of power on launch

Hi guys and excuse me for having a problem question as my first post here!

My E65 2002 diesel has an issue with accelerating on launch. There are no problems when I am already driving like 20km/h and pushing accelerator down to the end - the turbo starts over 2000 rpm and the car accelerates very well.
But when I am just going to start the drive from 0 km/h and pushing accelerator, it wont go over 1000 rpm until the car is not in move - drives several meters and achieves like 10-20 km/h speed.
The same applies when trying to launch the car. E.g. I have my left foot on brake and pushin accelerator with my right foot - the RPM will not go over 1000.

Guyz, any ideas? What can be the issue here? Has anyone had this problem?

Thank you all for ya answer!

No, not likely injectors.

When you hear hoofbeats think horses, not Equus quagga just because it sounds high-tech and mysterious.

I believe that Launch Control is an option not often implemented in diesel. Brake pedal defeat of throttle pedal is usual.

No mention of Launch Control here

Has it always been like this for the last X years or something that has developed?

No, it has developed. Like 2 months ago it had no such problem. I've identified it when I was trying to drive over a small barrier - the front wheel was touching a barrier like 20cm height and I could not overcome since rpm was not moving over 1000 and the car had not enough power. I had to go back like half a meter and try again with innertion.
