[Stevesalt12345]

Hello everybody good morning .
NEW TO CADDYS ... have a caddy sdi on 316k still going now starting to have problems...
I am looking to do 1.9sdi to pd130 asz or arl pd150 depending on location and prices .
Could someone please kindly explain and write a list off parts ect please
I have the edc16 ecu wonder could I use the asz ecu if demobilised , or how to get around ?

This probably has been covered multiple time . Any help would be great .

Thanks Steve
