One of the best investments for any owner of a modern diesel car is a cheap code reader. Given a code reader and a bit of googling you can find out most things. A cheap code reader will usually pay for itself instantly as it's less than taking the wagon to the main dealer.

"Anti pollution fault" is a generic message that appears on screen and can mean dozens of different things.

You need a diagnostic check to find what the problem could be. Search for "Peugeot Planet Owners Map" and you'll find a link to a map of Peugeot owners with Peugeot specific diagnostic equipment who will help you out.

They're not mechanics or garage owners so they don't have a vested interest in your wallet!

Don't go for a cheap code reader though. Not only will it show up old codes which may not have been cleared when a faulty part has been repaired in the past, but it won't read live engine data, confiming if the part is actually faulty.

I'm currently assisting a Peugeot owner who was given a code telling him that his EGR valve was faulty. He had the valve replaced but it hasn't fixed the problem.
