Hi, all, anti-pollution warning light came on, took it to a Citreon Dealer for a diagnostic, told it was the EGR valve, had that replaced by another garage because of cost. Anti-pollution warning light no longer on but I still have what I would call a stuttering of the engine or missing until it warms up then its okish. Initially this stuttering was made worse by me putting the air con on, but now that seems to make no difference. It's due to go back to the garage on monday, but as anyone got any ideas why it is like this PLEASE. Have spent so much money on it lately really getting fed up with it now. Its a C2 HDi 1.4 :(
