Hi everyone, I have a 2008 diesel berlingo, has behaved fine for a year and i have serviced regularly.I now have eco active in the display, i know all the general blurge about i have left the lights on, radio etc...but i havent. the battery is showing 12.9 volts, sometimes if i persist with the key occasionally it will crank and start. does anyone know if this can be programmed out, any suggestions to overcome what seems to be a system designed to scrap a lovely tidy well loved van.!! Any help would be really appreciated. chris
