Probably best to use a Lexia. My local Citroen specialist diagnosed a sensor, replaced it, and all was well when we had similar fault. The anti-pollutant system is a hateful addition on any car I'm beginning to realise. Our car has only done 50'000 but the pollutant system is always flagging up a fault and she smokes like you wouldn't believe, but we are fed up with spending money on it so it only goes to the garage if it has a genuine fault i.e showing fault and running rough not just showing a fault. Hope this helps, I'm going to buy a Lexia as I get charged a diagnostic fee every time it goes to the garage so it will pay for itself in no time. Good Luck and don't get me wrong I think they are great cars just wish mine was a bit more reliable.
