Hi, I have a Citroen C4 Grand diesel 7 seat 2008. After replacing the battery, I can not start the car. I get various error messages like defective gearbox, defective particle filter, defective handbrake etc. The lights in the displays turn on as normal, but after about 2 minutes half of the lights in the displays are gone and there is economy mode. When I try to start the car nothing happens? Do anyone have some idea? regards Terje
