This answer was rated:

Hi, I have a 2001 Xsara picasso 2l diesel. The engine management light comes on occassionaly on long drives, I have noticed reduced power when it comes on but the engine seems to be running fine and the light usually goes off again after leaving the car to overnight. Any idea what could be causing it ?

Hi sorry to get to you so late ,most likely due to our time zone difference ;-)..

Now after you doing a good drive distance and then the check engine light comes on and power is reduced, this is a sign of a problem with one of the emission sensors, this could be any one of the many you have controlling the engine system. .

What you will have to do is get your car hooked up to a diagnostic scan tool that the dealer has ,he will hook up and check for diagnostic codes ,from the codes he will then know where your problem is and what has to be done to repair this issue .

I have seen air flow meters cause this problem but have the codes checked to be sure before replacing any part .
