in the middle of 1998 Renault changed the complete central electronic modul
for all JE types. After that there were often problems regarding this matter.
Mostly the main problem is the modul behind the instruments.
Rear door locking:
Maybe only a broken contact or a mechanism defect. After I cleaned the
mechanism incl. using
spray everything is perfect.
As I remeber the satelite is runing directly in combination with the radio. Do you
have a radio in the middle box or a "(Grand)-Auditorium" under your front seat?
My Espace built in '97 has the old electronik components, that means without
the problems many owners are speaking about.
If you have further details regarding your problems I will open my ears for help...
