XANTIA HDi RUNNING ROUGH

[Rhothgar]

Seems your getting somewhere , even though its like stabbing in the dark,ive subscribed to this post I'm keen to find out what happens.

Those of us still with Xantia HDi (and other models) should perhaps be doing reference videos of their cars in a working state ie dash lights pre start-up and on start-up to create a reference of what we should be seeing.

The V4020 red light comes on mine on startup and I am not sure it should. That is the coolant temp light. Of course, some of us may have Exclusive models with more gauges.

I think it would just be really useful so we can support each other and know what the baseline is for a correctly operating car.

Good idea but too late for me

Rothgar
It is supposed to come on with ignition check lights and extinguish when started according to the handbook. Flashing STOP warning and red light indicates low coolant (plus overheating if temperature gauge is also high).

Well the Camshaft Sprocket and Hub have been removed today.

Skull's - Removed for Woodruff Key Inspection

Skull's - Rear of Camshaft Sprocket & Hub

^ The 'Woodruff Key' but not as we know it Jim (more of locating lug) intact. Looks to be all one piece to my naked eye, but on the photos looks seperate - tight at least and undamaged.

Skull's - Camshaft slot for lug

Camshaft slot to allow correct position of Hub.

Interestingly but unrelated to the current problem, looking at the various red paint marks on the engine and sprockets, at least the Cam Sproket has been off the Hub before I got the car (in 2015) as if I rotate the sproket 1 bolt hole I believe it will line up with the red dot on the cam cover on assembly. I never used those marks when I done my belt change in 2021.

Camshaft Top Cover will be the next area to inspect ....

[Huskyxantia]

Sorry for asking this , if its already been done (sorry) is the head gasket ok ?

[Skull]

Nothing to indicate it's Head Gasket related yet ....

[CitroJim]

At least we know the cam sprocket is intact and correctly timed Gary... The plot thickens...

[Huskyxantia]

Worth checking and you get to see the oil seal condition too.

[Huskyxantia]

Middle photos of the sprocket it has scrape marks on 2 sections, could it be possible that its been touching somewhere ,,then moving backwards the shaft itself is or has that been hit or warped ever so slightly? Just a niggle , hope I'm wrong

Good spot but that's historic I would imagine. It would surely be shiny if caught recently. Worth a closer inspection though for sure.

[Skull]

Yes I saw that and just thought it was very minor rubbing at some stage from either the cam cover nose or the engine lip. [EDIT] That’s the Cam Position Sensor (cam cover ‘nose’)

Skull’s - Cam Hub partially removed

I’m not concerned about it though HuskyXantia - I have bigger problems …

Maybe that’s why the Cam Sprocket was rotated, that would explain why the old ‘red’ timing marks prior to my ownership were out of line - possibly, as mentioned above it has been off for some reason.

Rothgar sent me some pages from his Citroen Diagnosis Manual....

Am I enterpreting this right in that the ECU may not or does not remember these faults

Jim thought as there was no temporary fault listed for the Fuel Pressure Sensor that my theory about the coolant shorting the connector out was wrong.

Where / How do you get the Fault Code 14 from then?

That's good at least its nothing thats causing it then, another one ticked off your list.

Do you not get them from here:-



or perhaps they are Elit or Proxia codes? Jim may well know.

Yes. You are interpreting it right. The ECU may not memorise a code. Don't ask me how. Maybe if there is no communication with the ECU at time of event would result in no code being stored. So my question would then be where else are they stored if not in the ECU? Very probably a chip in the dash perhaps?
