Anti pollution fault flashing up on dashboard

A sensor dirty or faulty most likely, usually is with C2's, lambda sensor.

engine ecu has fault codes to be read

several parts and sensors cover anti polution problems

Disconnect batt a min....see if it clears. May need it hookd to a scanner to tell issue. Emmisions can effect motor and computr

Don't change any sensors yourself. Contact Authorized Service Station or any Proficient Mechanic or Engineer, instead.

There is no such thing as an anti pollution filter. All modern cars have complicated pollution control devices on them, and unless you know what you are doing and have the specialised test equipment, there is little that you can do yourself. If there is a light on the dash, then you are going to have to take it to a Peugeot mechanic. They will be able to do a diagnostic test using a laptop and hopefully this will narrow the fault down. They will then be able to give you a cost estimate to repair it. It is unlikely you will be able to fix this yourself.

Finding a good garage is necessary for all car owners. Ask around for recommendations. You may be surprised to find it is a Midas shop or something unusual like that. They, and other shops that you only think do oil changes can do repair work.
Your problem may be that the car has gone a certain amount of miles, and wants something checked. Then the mechanic pushes a little button somewhere to reset the gizmo, and all is well.
Few people are familiar with Peugeots, so don't be surprised if it takes some time to find one who is. Mention that is is a Peugeot.

anti pollution fault with fault codes poo87 poo93 i changed fuel filter, so far all ok.

my 2008 308 shows anti pollution fault,what do i do now.? any help please

If the Anti pollution warning light is coming on the possible causes are endless. If the car is driving ok then that is a good sign, but please remember that modern management systems can mask problems quite well. The safest advice is to get it looked at and see what fault codes are appearing and then a diagnosis can begin, as leaving it is not going to be a good thing, it can go from a minor problem to more serious issues. At least the light is not flashing, which usually means an emission compliance problem and even more serious, but even so I would advise protecting your vehicle by getting it checked out as soon as possible to avoid potential damage.
----------
A fault in the ignition can cause an engine misfire and unburnt fuel gets into the exhaust causing the anti-pollution light to be triggered.

Check the ignition system for signs of damp or loose connections.------- I suggest get the car scanned at autozone service center.Its absolutely free to get car scanned.This will show the problem if you receive the error code.-------- Thanks.Helpmech.
