Since a temporary disconnect of the car battery my (3 button rf) remote plip won't operate the central locking. (Xsara II 1.4i 2002)
I have tried replacing the fob battery and following the instructions in the handbook to re-program..... ie, turn on ignition, press lock button for 10 secs, remove key, to no avail
Citroen say the code in the ECU must be lost - £65 to re-program (not for the transponder, the car starts fine).
I thought that the key programs the ECU for C/L, not the other way round ??
Is this a common problem ??
Any advice gratefully rec'd.
