hi there i am dean i currently work at peugeot and kia as diagnostic/master tech. i would be happy to assist you with your problems

With your depollution fault you have with your car a cat cleaner and fuel filter will not help the fault, The Light is basically your engine management light has came on, Your engine ecu will have a fault code stored in it. The best thing to do is have the fault code checked with a garage with the correct diagnostic equipment. Which will give you a fault code. Once you have this you will have a better indication where to look for the fault as it will tell you a certain part of the system.

Im sure kwikfit are reading fault codes, I would do this first which will save you money in the long run instead of throwing money at cleaned etc,

hope this helps, once you have a fault code and description come back to this question and tell me the fault code and i can assist you further,

The code should look like p0301 something like that.

Number 20 in the diagram is the fuel filter

It is underneath the car just in front of the fuel tank held in with one bolt, and 2 push clips for the 2 fuel pipes.


should take you 5 mins to change.

Hope this helps
