Without starting WW3...... I wonder if you own that bike? If I see something like that on a service invoice Id question it instantly.
After my last service. A technician left a comment in the notes. It said "Coolant low. And does not appear to be BMW Coolant"
I instantly question that. and pointed out, Only BMW have worked on the bike, so I need to know what is in the coolant. And I wanted it tested. Their response was "Oh it was a mistake, The technician is new"
According to SI its a formatting glitch within BMW's servicing software. Your clutch will have been serviced using Magura royal blood and engine using 5w40 engine oil, no such thing as Magura 15w40 engine oil and don't worry they wouldn't have put royal blood in your engine
