(now edited to include forum-hosted images - thanks chaps!)
This is my first foray with Lexia - thanks to a very kind local forum member who has kindly lent me his own kit, so that I could have a look at what is happening to our 2006 2.2Hdi C8. MASSIVE thanks to him, for starters!
Our C8 has been in my care for the last 75k miles of it's 150k-ish miles and it has been quite a family workhorse, lugging my our family of six dutifully about the place but now it's starting to require a bit of additional 'clout' to keep her going. I've done the clutch, D/M flywheel, clutch slave cyl, timing belt, water pump and a few other bits and pieces. Filled the eolys too. Here she is ... More recently, on longer runs, it has been going into limp mode (like the turbo no-longer blows) and a warning 'Depollution System Faulty' appears on the central console display. If I pull over and shut the engine off, let the canbus re-set (listen for the last relay to click off above the noise of 'Ah dad, why do we have to wait again?' and grumblings from the missus! Re-start and it goes back to normal for a while. It's been doing this for the last few months and I had also been re-setting the permanent DTCs via a cheap KONNWEI KW850 OBDII Diagnostic Scanner... which I now understand is really not the proper tool for the job. Owing to losing my job during the first coronavirus lockdown, my focus has had to be elsewhere - trying to find some income, rather than shelling it out on the old beast.
The good news is that after a bit of O/S sill fabrication and welding (more on that another time), she did sail through the MoT again and so I'm keen (financially keen too

This is where I'm asking for a bit of help - please!
The engine light is now on permanently and although the car seems to start and drive fairly normally, it would be great if someone could be kind and point me in the right direction with the DTC codes I've now extracted. Must say that Lexia-Diagbox is clearly quite a clever bit of kit, especially when you consider when it must have been compiled. Would love to have my own version of it at some point.
So, here goes - any pointers much appreciated please - thanks in advance.
Here is the response from the Global test Here are the ignition/injection codes And one that might be driving the Depollution system faulty notification?? or could it be time to notify the fill (I didn't do this when I filled the eolys tank with more fluid) (Recent edit 02/02/2021)
Also seems to have a fuel filler cap sensor - now not reading correctly. Expect it can't work out how many times the tank has been filled as a result. Gather this affects the Eolys dosing. Got a comms error with the cabin heater this winter too - bit of a pain when it is very cold but this is not the priority at the moment, it'll have to wait for now! If there is anything specific that would be useful to know/see, please let me know and I'll pop another image up.
Hearty thanks in advance,
