Hello friends. I need your knowledge. I have a 2001 Jaguar xj v8 souverign and it has not started at the first time for a month. It does the diagnosis and says "Engine protection" and "stability control faulty" and it does not start. I try it several times and in the end it starts. I put in a new battery two days ago with 12 volts and 850 mA discharge and it remains the same. Has this happened to any of you? It has been passed a diagnostic computer and they detect nothing, everything is fine. Once it starts, I can stop and start it as many times as I want. but I use it very little. I do not know what to do. I await your advice

thank you very much
