I own a Peugeot 307 2002 1.6L Hatchback and owned it for the past 5 years I am the second owner. The car is not driven very much but is still in good condition, as I do yearly services. However it has been off road for a couple a years and the last service I did was January this year and everything was fine. I turn it on and drive it a couple blocks once a week to keep it going but about a month ago it wouldn't turn on, I just thought flat battery so I went and brought a new one but only yesterday so the car was dead for about a month or so. It turns over but the engine wont turn on, and the dash is saying economy mode active, my partner has checked the fuses and they seem fine and not burnt out. The inside lights turn on, the headlights turn on, The radio and break lights don't turn on, the indicators only turn on when you press the hazards. I cant get the windows or the central locking to work either so it is currently unlocked. Not sure if this is a computer problem??? Your help would be appreciated. Im going out of my mind and its a very costly car!
