Hello this may be an issue with the FAP system In the exhaust is a soot filter known to PSA as a FAP. It runs very hot to burn some of the soot off every few thousand miles. It uses an additive is called Eolys and is stored next to the diesel tank with a computer controlled dosing mechanism.+If you don't drive it long enough, fast enough; then the regeneration process won't commence and the filter will block. Take it for a 40 minute blast down a empty dual carriageway; As you need to maintain above 50mph for around six minutes - that will start the process. Alternatively; take it to your dealer or Citreon specialist for a forced regeneration. If it's done more than 50,000 they will probably just fit a new FAP and top up the additive. this will cost £6-800.

you mentioned deisel,mine is a petrol model. does this affect your diagnosis?

Hellothanks for the extra information that does effect things and in which case its likely to be a fault with one of the oxygen sensors in the exhaust or it could be a blocked cataylst as the next step I'd suggest trying a bottle of this http://www.cataclean.com/ if that doesn't help then I'd get a fault code read off to point to which sensor is at fault
