The problem can reportedly occur if the in-tank electronic fuel pump isn't properly activated when the fuel pump relay is energized at vehicle start-up.
Beginning August 30 of this year owners of affected vehicles can simply take their faulty cat to the nearest Jaguar store for a free software update that should fix the issue.
