You should be able to find this information in the technical manual ( as I see you are listed as a full member). Click on "Technical Manual" then to maintenance.
I just finished the annual chassis lubrication for my car, and it was 17 points (the center coupling on the drive shaft does not have one on my car) so that would make eighteen.
Your best bet is to find an owner's manual. They are not all that difficult to find, at least on ebay in the US. Patience, and you will find one.
