SACH1965

Hi All, New to this forum and have just got my first jag. Had a merc before and must say glad I got the XF. I have had the issue with the start/stop since i got the car and the dealer mentioned the possibility of a faulty battery. They have replaced it since then with a 95Ah 850A. They said that the secondary smaller battery was only 75% charged and therefore they had charged it further. Since then I took it for a very long run and still the start/stop doesnt work.☹️ Looks like a return visit to the dealer. I have read suggestions of resetting the ECU/CPU by removing the -ve terminal and touching it to the +ve. Has anyone tried this suggestions?
