Hello Ryan.
Welcome to the Club.
Does your Stop/Start work, I had to get a new 12 Volt AGM battery and it now work's perfectly, i would ask them about the Ad Blue because it's stated that if the Container is Over filled it can cause problems and could cost £160 pounds to get it sorted.
Make sure all your Door Locks, Heated Screens and electric Windows work.
And for Servicing find a Good Independent jaguar Garage, you may have a good jaguar dealer, but in the UK there are some that haven't done a proper service and some owner's have had there Dash Cams dismantled with cables hanging down from the roof lining.Probably to stop the owner from seeing what is going on in the workshop.
Regards Tom.
