Range Rover sport 2011 restricted performance

[Nabeel300]

I have Range Rover sport 2011 and after I change the water pump and cooling system start giving me yellow triangle ( restricted performance ) and the car has no power
What could be the problem?
Thanks

Maybe a sensor did not get connected. It would definitely not like being able to read your coolant temp and you dont want to fool around with that either

I have a 2010 Range Rover Sport Supercharged and recently mine start to show "Restricted Performance". I shut down the engine, removed the Mass Airflow Sensor plugs and firmly reconnect it, restart the engine and drove a few kilometres. It did not came up again. If it come up again, I want to check my air filters. Hope it helps.
