Whereabouts are you? Have you had the ECU read by a Lexia? If so what were the fault codes?

Lol, bless ya, the Lexia is actually the official name for Citroen's diagnostic machine & isn't part of the actual car. If you take it to a main dealer they will almost certainly connect your car to the Lexia & then read any faults in the ECU's. If it's not running correctly then the most likely place to find a fault would be in the injection ECU, it's actually possible for the dealer to try a software download/upgrade direct into the injection ECU by using the lexia (if the software in the ECU is already uptodate it will not take a download) but as there are no actual parts involved it's not usually an expensive job & is usually quite easy for any main agent to do, having said that i might have tried doing a download first before replacing any parts so it may have already been tried.

If it is an auto it can be unpredictable at times. Mine revs up and done and changes gears at strange times.It is teaching me.
