Hi all,
My name is Paul and I am looking for some help with a 2004 Viano,
My inkling is its the Sam unit but just to be sure I am not missing anything, the vehicle has no left indicators and some issues with the central locking, sometimes works of the buttons some times it doesn't. Anyway have done a continuity test and that's all OK, is there anywhere else the fault my preside, check on our autel system and says short circuit Sam failure. ??
somebody help...

:wallbash:Hi all, so has anyone come across similar issues? Anyone have a wiring diagram for the Sam? Any help would be really appreciated, Sam unit winging it's way to ecu testing, hoping the find something. But any help in the meantime would be great?
