Hi My 2006 2.0 Hdi C8 gave me an immobiliser fault, as a first option I tried the reset procedure, you know...window down, disconnect battery, reconnect battery, lights on, etc, etc. However all that happened is that the car is now stuck in economy mode with the drivers window down. I have Lexia 3 with Diagbox 7.2 software and tried to reprogramme the economy mode to off, i.e. zero value however when trying to confirm the parameter change the screen comes up with: 'operation possible but access code required' 'input access code *****' I don't have a five character/ digit code, the key code is 4 digits and does not work. Does anyone know the code or where I can obtain it? Thanks Bob
