I have got a peugeot 607 2003 plate which has got a warning message coming up every time i turn the car on which says something like "Anti Pollution System Inoperative" coming up on the display panel. There is also a picture of what looks like the engine block coming up on the screen. I havent got a manual for the car as I have only had it a couple of months and am unsure of what this message refers to. Am I damaging it more by using it whilst this message is showing? Is there anything I can do myself?
