French fault codes

[Plynchy]

Morning all. Currently half way down France, been doing a few long motorway runs at a steady 80mph on cruise, got a CEL light up yesterday, van still running fine, air ambient around 35c (it’s bloody hot).
Checked the codes when we got to Orleans, had the following, which have both reset ok.
Got another 200 miles to go today, is it worth getting some additive put in?
Any advice welcome!

Emissions reduction stuff, Adblue / Nox Sensor things - Could be a dodgy sensor, poor Adblue quality, issues with the EGR system... But the first fault code i think is more to do with the Adblue system itself, which causes the second code.

Do you have the Adblue no restart warning?

No, not yet anyway

Does your iCarsoft report on various sensor data ?
It would be useful to get data from the Adblue system on qaulity of the ADlue fluid, and other parameters to determine why it is throwing up the fault.
This can be done with VCDS, but not sure about iCarsoft.

There seems to be a separate couple of threads of this combination of fault codes, with one pointing to issues with the injector I think. Might be worth putting in some adblue anti crystal stuff, and/or fresh adblue perhaps. In Europe you can get AdBlue more frequently at a pump, I'll never get it again in a bottle

Useful info all, thank you. Will check at my next stop this evening to determine what data is available, that’s presuming I get there.

Another 270 mile run today in very high ambient temps, no further codes which is nice, sitting around 80mph for most of it. Put a tank of posh diesel in though which may have helped

If needed we saw the AdBlue additive (anti crystallising stuff) in the car accessories aisles inside big LeClercs. Sure it was about six euros or something like that. Seems pretty common stuff over there.
