Hi, just wondering if anyone can help. I have a 406 glx 2.0 petrol estate 2001 (Y plate). Last night when driving home from work the engine management light came on and i got a message saying 'antipollution fault'. The car seems to still be running fine, the miles per gallon don't seem to have changed and I haven't noticed any other changes or problems. I wondered whether it was just a one off and would go away if left overnight but having left the car and trying it again this afternoon but I still get the message and the light on the dash. If anyone can shed any light on this problem I would be most grateful. Thanks in advance. Guy
