My car never has any problems. I'm driving along, suddenly every one of the Faults and warnings appear on my dash. I can keep driving okay. Temp says HOT so I pull over. I stop and turn off the car. It won't start up. No dead battery or alternator problems. I did notice my steering got slightly firmer, but no prob really. A/C and windows and radio work. Just won't turn over, and all FAULT warning keep appearing in order. Checked most all the fuses, none damaged. What happened? Can I get this car going by removing the Codes sent wrongly? Also, no air pressure in suspension. I want to get some info before I tow it to the shop. What could cause an instant error on all warning systems when the car was driving fine?

 

Welcome to the forums. Your car is a X350, so for better assistance, post on that forum.

But it's still a Jag, so try a hard reset. Disconnect the neg. cable at the battery and touch it to the positive post for a few seconds. This discharges capacitors and causes the ECU to re-address the other modules.
