Do Citroen Know Anything On These Cars

[Guest c5 headache]

hi, thanks for your post, i do have that info however it only states that for the car to start it needs a required pressure of 5bar like a diesel needs 8bar, what it doesnt tel you is the pressure boost, if a pump is giving the engine the required boost it will rev and run correctly,however if the boost is not there it wont rev up correctly inturn creating a fault. As my car now revs up great and holds at those revs i cannot see why it kicks into limp mode as for it to run correctly the pressure must be there, however without a set of figures that are citroens own data or a comparable set of a running hpi moddle i cannot go to them and say you have wrongly diagnosed my car, they would just say that the figs i am going of are the ones needed to start the car and keep it ticking over.

 

Thanks for the info though

Have you tried reinitialising the injection ecu using the following procedure:

 

Erase faults

 

Engine cold :

Switch on the ignition & Wait 20 seconds

Start the engine & Idle the engine until it is hot enough to trigger the cooling fan - make sure air con is off.

 

After cooling fan has activated, Drive the vehicle on light engine load

Change through all the gears.

Take the foot off the accelerator several times (from 3500 rpm to 1500 rpm) - allow it to decelerate.

 

Switch off the ignition & Wait 1 minute before restarting (7 minutes in the case of the cooling fan running on after ignition off)

 

The reinitialisation procedure is complete

 

Start the initialisation procedure with the engine cold, if the following components have been changed :

Proportional oxygen sensor (upstream of the precatalyser)

Exhaust gas temperature sensor (upstream of the precatalyser)

Exhaust gas temperature sensor (downstream of the precatalyser)
