You need to invest in a CTEX MS 7 or MS 10 battery charger/restorer and keep your battery well charged at all times. My S Type goes on charge at least once a week for at least 24 hours. Jaguar are prone to Parasitic Discharge and will cause many faults and problems if not kept on a high charge,

Hi Tim

The low voltage of a flat battery has probably corrupted one or more of the many computer modules which control everything in the car (hence Wrinkly's advice on using a CTek which many of us do). A flat battery during first lockdown in mine resulted in non-unlocking rear doors and non-functioning rear windows.

The solution is probably to get the software unscrambled. Jaguar dealers will probably want an arm and a leg but garages with the Autologic diagnostic systems seem to be able to sort quite cheaply. I remember there is a garage in Sutton Coalfield(?) which has been mentioned here a few times but probably not viable from Cheshire as you can't get it started. I would ring round Jag specialists in the North west. Jagman in Wigan has a good reputation and I think there is one in North Wales and another in Liverpool that have been recommended here.

Good luck

John
