Plus one for battery but it also might just be a speed sensor. I had similar problems on my previous car and a £30 sensor restored harmony. Hope you get it sorted without too much hassle. Pete.

What kind of daily mileage are you doing? My first thought is that it may be due to a partially discharged battery: Jaguars throw up all kinds of spurious electronic warnings if the battery is not kept fully charged, and coronavirus restrictions have resulted in a lot of poorly charged batteries. I keep my XK on a CTEK battery conditioner if it is not doing decent runs, so the battery is always fully charged, but I did get such warnings before I started doing this.
