My jag xtype 57 reg as a intermittent error were the dcs fault is displayed or a fuel consumption computer error this

These problems usually are not related.

I think we have a problem with one of the traction/brake sensors. Usually when just the DSC warning is on without an ABS warning this is a DSC sensor like the steering angle or Yaw sensor. I have also seen some issues with the control module itself as well as low battery voltage so we need to have the battery and charging system tested.

For the fuel data error I suspect a problem with the in tank fuel pump. There are two fuel pumps inside the tank due to the saddle design tank. There are fuel level sensors on each pump which tells the instrument cluster the level on both sides of the tank. SInce the tank needs to be removed I would recommend both pumps to be replaced. we should run the test on the instrument pack. Pres and hold the trip button on the turn signal stalk then turn the ignition on while still holding the trip button. Once in test mode the message center may say engineering test mode, ETM, or test. You will see the gages do a sweep test. Press the trip button to cycle through the test. The lights will be displayed and you will see some info on the message center. You are looking for the raw fuel data. It will say F1 or fuel 1 and F2 or fuel 2. Those are the senders and it should read a number. At full they should both be around 230 and about 60 empty. They should be close to one another when above 1/2 tank but fuel 1 should be more than fuel 2.
