No turbo when I press on the gas pedal, revs high but no power.

What is your question?

Was heading out to work and noticed that when I pressed on the gas pedal it didn't cause the vehicle to go any faster. I eased offor of the gas pedal and tried it again, noticed that my engine light came on but proceeded to work (not far from home) . Got off work and light was still on and as I when I pressed on the gas pedal, I experienced the same hesitation. It would rev really high and eventually I would get a knee jerk reaction. Ok at speeds under 40 but anything over that then I get this reaction. I have a 2013 Range Rover Evoque. I've had the vehicle for close to 3 years.
