Citroen 2.0 HDI power loss - bhighe
I have an intemittent fault which my dealer cannot find because it does not show on the diagnostic record. After about 30 mins at motorway speed, the power falls suddenly, I would guess by 50%. I can drive at any speed downhill, normally on the level and slowly uphill. A quick engine stop/start clears the problem until it occurs again maybe after 5 mins, maybe next day. This suggest that it's electronic and the car is OK running around off the motorway but I have no more clues.

Its going into limp home mode the restart resets the ECU now to find the needle in the haystack.I would look at sensors as some of these are not recorded by the ECU but the Cit ECU is very good and a link up to the dianostic setup at a Citroen agent should find the fault.
