Hi, I have Peugeot 307 SW 52reg.Antipollution fault light come for 2 nd time.First we changed the antipollution valve for ~350£.Any other ideas to fix the problem without spending to much money?Thank you

if its a diesel most peugeot's have a extra tank hidden under car that has treatment for the exhaust/cat to work more cleaner.....if this treatment needs topping/or blockage etc it will bring up a picture of an exhaust on the dash stating antipollution fault....its a dealer fix proccess cause not many mechanics know what to do or even know its there.
the manual will tell you to drive at a certain speed to correct fault but if this doesnt work it will need attention a.s.a.p to prevent other damage

i had anti pollution showing up on a 406 eventruly found it to be the fuel regulater valve on the fuel pump ( if its a hdi diesal) cost £275 just for the part dont get a second hand one and fit your self as it needs to be on computer to programme it to the car
