Hi mariobianchi32
Unfortunately the DTE or eLearn version for the X230 Ducato was never found on the net, originally there was a X230 eLearn available (to restricted service places as usual) but unlike the DTE & eLearn versions of the X244 & the eLearn X250 versions the X230 eLearn version have not appeared "loose" on the net.
There are non Fiat printed versions available in languages other than English available, one in German, not sure what the other one is? Both of these have been scanned into a PDF form & can be found on the net.
From what I have seen the original 230 eLearn (along with the newer versions) info is still available in the new KeyLearn Fiat Professional USB - if you can buy it @100 Euros, again to authorized service places only.
If you want to obtain one of the scanned non Fiat PDF versions (not English) PM me.
Cheers
