Hello and welcome :)
Best to ask over in the range rover section of the forum, and give as much info as you can as to engine
 
Welcome Digby, A previous Vouge of mine went into limp mode due to one of the map sensors on the one of the air intakes, after having them replaced under warranty all was good for a while. Best get the codes read and see or spray the map sensors with contact cleaner and see if it helps.
