It is very difficult to determine your fault as it all points to emissions etc,has your cerine/eolys tank been topped up?particulate filter re generated?code reader codes found?EGR valve ok and clean?When people purchase these French motors eg,Peugeot/Renault/Citroen then they need to realise the costs that can be associated with them,myself?I steer clear of any of these and if you look on this site then you realise the problems that come with them.
