If the CD that you bought from eBay is Fiat eLearn, then that is most probably the best that can be obtained. Another member of this forum has described using eLearn as "like peeling the layers off an onion". However I should point out that I have discovered several errors on eLearn wiring diagrams.
In order that you can compare your CD with eLearn I am adding a link to the Russian website 4cardata, which carries an incomplete copy of eLearn.

If you can unearth something on the lines of a Haynes manual for the x244 Ducato, please inform the forum, as it is most likely to be of interest to members.
