Adblue error messages
From diagbox
2017 C4 GP with 19k miles only. Had it since new,
Does anyone knows where this part is? I bought secondary pump unit but still no joy

Is this urea gauge-pump module inside the sealed tank or can anyone please point at it on the photo.
Cheers

No - these are sealed. It's a new tank most likely, you can't repair these as the tanks are sealed. The picture shows an example of one that has been broken open, rendering it useless, so was probably for investigative purposes.

It has not been unknown to get a good will gesture from your dealer to part cover the costs. A lot depends on whether it has been regularly serviced or not. But these are known to fail for various reasons.

The photo is mine and the pump and electronic parts you see is attached to the tank by 12 Allen screws so it's not broken, however you partially right as the tank itself is sealed and can't be accessed unless you know how to reseal it, which I haven't researched for that yet, hopefully I don't need to go that extreme!

Ok, thanks for confirming. I think you'll find the rest of it is heat-sealed and can't be got at without cracking / destroying the plastics, and why faults with these do necessitate a new tank - which is why they are quite expensive, as they contain all that you see and none of those internals are sold separately.
