engine management and loss of power
 

Hi guys, has anyone had experience of the following issue - driving my C30 D3 2.0 today and when pulling onto the motorway and accelerating, the power just nosedived off and wouldn't rev over 2k so I assumed it was limp, pulled over and switched off and back on again, problem solved, no problem.

Made it home and decided to check after 15 minutes of being switched off, had a lot of trouble starting the car, when it did start, engine management light came on and is still on but the car drives OK, no loss of power or any other fault.

For info, 30k miles, 61 plate (2011)
