wow it sounds like an interesting procedure, have you done this with many vehicles?... I'm worried a little bit if the Diesel residue might cause any damage
Done it many times. Diesel is a solvent and helps dissolve gunk, draining it before running it prevents any damage. The 5min idle with any ll01 allows oil to citculate and displace any remaining diesel and when you drain it you'll be disgusted and how chunky and smelly and nasty it comes out.
With all the goop out, fill with clean oil and carry on.
I would be tempted to repeat the process a second time (just filling the oil pan with diesel, not entire engine), to ensure no particles are clogging the oil pickup screen.
