Help, poorly Mini

[RVVUNM]

I have a Mini Cooper S 03 and I love it, but I have a problem. When its warmed up and I rev it to 6000rpm it cuts into limp mode and the engine warning light comes on. If I turn the ignition off and on again it starts back up as normal but the engine light stays on. If I then let the car cool down and start it the engine light goes out as normal. I wonder if its anything to do with the CO2 sensor.Any ides's out there?

Thanks,probably the way forward but I was hoping a technician may be on line and had a tried and tested solution.

No not at all, just that this is a motoring forum and there are many people with endless knowledge on many different car problems. For example I had a poor running MX5 once and the solution was to change the rear temp sensor, a sensor I didn't know existed until someone on here told me, £15 later and the car was fixed.
