Not sure what engine your X5 has (3.0i, 3.0d, 4.4i, 4.6iS etc.) and it matters since there are some wiring differnces between the versions.
But no matter what engine you have, I doubt you'll find a single diagram showing all the ground points - there are dozens of them.
What specific problem are you chasing (in relation to ground points)? Is this the excessive current draw?
It's unlikely a poor ground connection will casue an excessive current draw - rather more likely the opposite. Bad connections tend to
decrease current flow in circuits.
I'd direct you back to your other thread about this issue but that one has sadly already gone off into the weeds...
If you have access to wiring diagrams and understand them to some degree, then try to isolate various systems to exclude them one-by-one. Fuses can pulled to do this, but start with e BIG fuses, then work you way down to the smaller ones once you isolate with sub-system is drawing the current.
