Y en una web... Encontré esto..
BEA 700 020
En teoria vale para los motores chfa...
Pero tb pone que es esto...
complete kit for installing cruise control in the Roomster/Fabia II, only for vehicles with a dashboard computer, includes wiring, cruise control lever and assembly instructions, intended for vehicles manufactured before MY 2010 (pre-facelift)
Asi que... Seguiré investigando
