I'm not sure what this could be. It would be worth asking the ECU if it thinks there's a problem with, say, the Suction Control Valve (which may not result in a Check Engine Light, but will induce limp mode). You might need to ask the ECU when the engine's cold.
If it is reporting the SCV as a problem, it would be worth checking that you don't have a leak in the fuel system that's allowing air to seep in while the car's stopped. It doesn't need much to trigger this - just a bit of air is all it needs, and if your car starts and keeps running but still gets this error, you are lucky in that you've caught the error early.
One way to test this completely: before starting the car, pop the bonnet and squeeze the fuel primer heaps, then drive it and see if the problem's gone. When mine started playing up, I'd squeeze mine about 30 times to prevent the error happening. Once I had the bad fuel line replaced the problem was solved.
