Had a 615 in a 220D had pressure like that as I recall, never was a problem. Ran really well.
The oil pump is easy to change on that car and a couple of bearings are accessible through the lower pan.

The mechanic will replace the oil pump this week and if that does not work we will change the bearings.
This is an issue affecting tons of people from what I have seen in these forums and reddit, so I will make sure to share the progress in case others have this issue in the future.
