I found a YouTube video on jaguar secret computer access. You select Navigation, then hold the colored bar above the navigation menus. Hold it about 10_20 seconds. Then a keyboard will pop up The codes I got so far are as follows:
660 Diagnostics menu
662- GPS
661- Systems Check
944 Service
Does anyone have any other codes and does anyone know how to reset the service light?

 

To re-set the service interval indicator, the following process switch presses must each be carried out within 3 seconds:

• With the vehicle in power mode 0, (ignition off) press and hold the rear fog lamp switch
• Allow the vehicle to enter power mode 6 (Press the start button without a foot on the brake)
• Immediately release the rear fog lamp switch
• Press and hold the trip computer cycle switch
• Press and hold the rear fog lamp switch
• Continue to hold the trip computer and rear fog lamp switches
• If the process has been successful, the message center will display 'RESETTING SERVICE MODE' and then display 'SERVICE MODE RESET' after 10 seconds
• Release both switches and return the vehicle ignition to off, power mode 0.
