Citroen 2008 C5X7 2.0hdi Injector problems

[Desert Frog]

Hi I have Citroen c5x7 2.0 hi vin VF7RWRHRJ54067893 with 337000 klms on it which has started to play up so I put my diagbox on it and I came up faults with engine speed went and injector flow correction was weird (see photo), I start to do a test which was showing two and three going all over the place and one and four running steady on zero then the car shut down and diagbox computer went flat. Can some who knows help me, I live in Fitzroy Crossing in the Kimberley, the closest Citroen dealer is in Perth almost 3000 km away, and we are currently completely shut off by road due to massive road damage from flooding.

The image was shrunk too much to read. Can you try a jpeg with much higher quality?

Hi due to loosing most stuff in the floods I am only using my iPad and can’t seem to convert the image to jpeg and this forum won’t allow me to post larger files however cylinder injector 1 flow correction was -64.71, injector 2 was 37.25, injector 3 was 33.33 and injecter 4 was -13.73. When I doing a live test the graph on 1 and 4 was a flat 0 and 2 and 3 were up and down and far from consistent even though the revs were, there doesn't seem to be noisy injectors although I am aware that when you are always driving a vehicle slow developing noises you can catch you out, and you not realise how bad they are till you fix them.

Hi Seasink if you want I can give my email and if you email me back I can then email you a much better image

I may not have your answer. There are others with more RHR experience than me. Much better is to load a readable picture.

In my experience Apple makes everything harder than it need be, but there is an app, Compress Photos & Pictures that can do the trick for you. The original at 60% quality will likely do the job.

You can read about some Apple imaging abilities at https://www.igeeksblog.com/how-to-reduce-photos-file-size-on-iphone-ipad/ Most need apps.

The image can have the dimensions unchanged with a suitable reduction in jpeg quality.

Alternatively just list them out in order from Diagbox by typing a table.

Are there any OBD error codes?

Hi managed to get some images compressed, let’s see if I can upload them. Ok so first photo is list of fault codes, second is the photo of injector flow correction figures, third,forth and fifth are photo,s of live data flow correction. I am some what confused as I am used to flow correction in percentages 100% being great either side of that too much indicates a problem. I might be on the wrong track completely as when car is running it does not seem to run rough or noisy. It runs fine then just shuts down. Turn it off then on again it might go good for 10 minutes or even an hour then suddenly shut down. Anyway I deleted all fault codes then ran it until it shut down again and the list of fault codes that came up is the list pictured. Appreciate any help as I don’t know where to go from here. I had it do a similar thing happen before shut down four times in 900klms (round trip to Broome) when I checked out with my diagbox came up with stoplight not working, turned had a broken wire on then led stop light in the back door, repaired that and no more trouble and that was June last year and 30000 klms ago and nothing till this. Thanks Warren

I would be looking at the crank sensor and or connection to it very common to fail also the magnet on the crank pulley end can become damaged but sounds more like a sensor those injector corrections aren’t a big concern

Thank you will look into it
