Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related.

When this happened to me on my seven year old 2.2 DCi laguna I had to hae taken in to the Renault dealers. It turned out to be the a problem with both the cam sensor and the fuel injection sensor. Both had to be replaced at a cost 0f £300 in all. It did cure it though! May also be TDC / crank sensor. Worth removing it and giving it a clean.
