Any one no why.

 

Almost certainly due to a low battery voltage. If the battery is less than 5 years old then make sure that it is fully charged and see if the messages go away. If it is older than 5 years then replace it with a fully charged new battery.

2nd most likely cause:

dirty wheel speed sensors

or

broken wire on wheel speed sensors
( the sensor harness is too short and full lock turns out a strain on it, imo )

@RichardS suggests, a low battery is the primary culprit.

and not only in this one case. A low battery will cause many problems. Resulting in all kinds of warning messages including the dreaded engine failsafe. As well many other less ominous ones.

Unless one’s battery is too old to hold a decent charge, it’s very beneficial, even critical, to keep the car on a legitimate battery tender whenever the car is parked overnight or longer, in my opinion. There are several brands that have been endorsed here, including the Delran Battery Tender +, the CTEK, the NOCO Genius series. There might be others, but those are the top three I see mentioned most.

There are several theories why these cars benefit so greatly from a tender. My thinking is that the wiring and modules have more resistance to electrical flow than when new. A less than fully charged battery doesn’t provide the needed voltage anymore. The alternator will maintain the systems when the car is in motion. But it won’t bring an 75% battery up to 100%.

Kenny- you say code issues but codes are what you need to end the guessing. You need to buy a code reader that can display Jaguar specific codes or take it to a shop that read them. Another common problem is poor solder joints in the ABS module.
