hello this means the engine control unit has detected a fault with the engine , or has a sensor thats faulty and in order to play it safe the engine performance is limited until the problem can be further investigated your next step should be to plug the car into a diagnostic device to read off the fault code and so point to the faultobviously most garages will charge for this service but its well worth it to narrow down the fault finding and fix the fault speedily
