Hi I have Peugeot 307 for about 9 months and about 6 months ago I keep getting a message on the trip computer "anti pollution fault". I also get an ECU light on the dashboard. The car runs fine and still has power. I have done some research on the internet and people are saying that it could be the manifold or oxygen sensor. Has anyone else has this problem? Or is there anyway of me trying to diagnose this fault.
