ae, tirei de um site gringo:
I had something similar happen to me a couple of months back. It started with ASC light, traction control lights on and limp mode. Turned the car off and back on and it was fine for about a week and then it happened again. Restarted, all good. Later that day all the lights came back on with the engine light this time.
We took it into Mitsubishi the next day and it turned out to be a blocked MAP(Manifold Air Pressure) sensor, which I believe is a design fault. They fixed it for free (under warrantee I think). I'm not sure exactly what they did but they did take the inlet manifold off and if I remember correctly they replaced it. The MAP sensor I think is used mainly to control the turbo.
If this is what has happened to your car then at least you know that it is a common fault.
If you search for MAP sensor you will probably find a number of posts about it.
