Hi Everyone, I am new to this so you will have to excuse my lack of car knowledge. I have had my Chrysler Delta for about a year and a half its the multijet 1.6diesel auto 2012. Everything was fine until about 8 months ago when the battery had died . I thought nothing of it and changed it . The car then ran ok for another 6 months then the battery died again. I managed to jump it and took it for a long drive to charge it. The radio now had power but wouldn't turn on. The battery continued to drain and has been an ongoing problem since . I took it to Halfords for a diagnostic check and they gave me the fault code P0685. I believe this relates to the ECU and they wouldn't touch it. I've since had an auto electrician out who also couldn't solve the problem. Before I go to a main dealer can anyone shed any light on the matter? Over the last week things have got worse and a transmission fault light has now appeared on the dashboard and the car only drives in first gear in auto and 3rd gear in semi auto. Could it be something simple like an ECU relay? , or something much more serious? The car is currently sat doing nothing on the drive as it is unsafe to use . Please Help !!!!
