Hi All I have a 2.0 Hdi Citroen version of this van but it has the Fiat 3 pin diag socket and Fiat keys. It recently went to the dealer for the keys to be re-programmed (as far as I know thats all they did) but they seem to have failed again. My auto elec says that to re-program these keys it is a case of disconnecting the PCM and the immo control unit for a while, then reconnect and use the original key to a sequence? As usual AD is about as good as a chocolate teapot, even looked through all the other Fiat stuff. I am also told that the PCM can be reflashed to bypass the immo. The cutomer is happy to go down this route (not much crime where we live ) but I would like to find the answer to the reprogram problem first. He is also very loathe to return to the dealer after his previous experience. Any suggestions greatly appreciated. Regards, Bryan.
