This could be the lambder sensor or the catalyst is on its way out, bare in mind though these computers are sometimes wrong on this model so get a second opinion from a garage. Sometimes they just need a good run out or a sensor cleaning.

    Hi then the fault must be the EGR valve, this is a Exhaust gas recycler valve, it basically takes all the unburnt fuel and pushes it back through the engine so to reduce waste and reduce emissions,
    I pretty sure thats the fault from the details you have provided. Second hand they are about £30 new maybe around £100. the car will lose a lot of power with this fault adn fels like the accelerator is not working properly when you push down on it.

    Regards

Citroen C8 depollution system faulty


These motors and some other models with the same system always give problems .Havent done one myself as yet but other mechanics have that i talk too and if this is a diesel which has this system then you remove the particle filter on the exhaust system and make a rear box to fit type job and the sensor you disconnect and solder a resistor of around the 10.000 ohm mark across the sesnor wires to make the computer think all is well .Depends on the year though as to weither this will work satisfactory as a 53 plate sounds misteriously like some sort of secret code to me .Just noticed it says petrol 16v Hmm have to think again here as no idea with this one only ever see a diesel variant but if the cap fits so to speak have a look to see if has got a filtering out exhaust system if not then sell it quick and buy a ford or a VW

Depollution system faulty peugeot 308


Well its a 2009 and as such its all electronic control and it can only be diagnosed using the dealer software via the internet this is to stop people like myself from doing anything to it ,from the sound of it i would suspect the throttle position sensor under the dash on the end of the throttle pedal as this fault i have had before on more than one occasion even more so with my favourite )not( make of vehicle a renault but in all honesty you are in the hands of the dealers here as they are the only ones with access to the software via the internet with the factory ,Sorry i cannot give you a nice fixya easy type fix
