Confused with shown EOLYS/FAP levels

[bus92]

Hello there!

Long story short, I have a 308 T9 2015 (1.6 bHDI), which has had FAP refilled at around 30.000kms before. Today i noticed via an Autel MaxiAP2000 diag tool, that there are two different values shown regarding the remaining FAP content. One is 902ml (seems realistic), other one is 0.
No errors on the dash, and that number is decreasing which I assume it means that it gets injected into the fuel. Only one DTC was visible with the diag tool: FAP level low, which can be a remainder from old times, not sure.

My question would be: is it a problem? Maybe the dealership forgot to reset the counter on refill? Why does this information even stored in multiple places? Will this be an issue because it believes that it’s empty, and will not add FAP to fuel, or if that 902 number keeps decreasing I don’t have to worry about it?

Any input is appreciated.
Thanks!

There are things that aren't clear because we don't know like what dealeship done. The values of eolys that is used seems right for the distance of 30k. If you use another diagnostic tool you may not have confused results like in Diagbox where there is only one field for remaining quantity.Usually eolys fluid lasts for many thousand km like in my car which has a 1.650 ml tank and when i fill it up i suppose for first time and just added one lt. of eolys in 140K km. Have in mind that the system just calculates with a start point of filling it up and resetting and then from filling the fuel tank every time and how much quantity of fuel.There is no physical measurement. In my opinion if you have your doubts and just to know where you are and , if you can yourself or if you can check in a garage, empty the eolys container, see how much is there, fill it up and reset it with a diagnostic tool that can do the job.

Thanks for the answer @LedZep!

I tend to believe that they indeed did the fillup correctly, as it was a Peugeot dealership, but of course, everything can happen. I also do believe, that if the EOLYS pump would not been able to deliver fluid after diesel fillups, it would issue a permanent error, e.g. it'd bring up the check engine, or the service light, but correct me, if I'm wrong on this one.
Anyway, I'm going to monitor that value, if that is decreasing after diesel fillups, and if the intermittent "no diesel additive left" comes back.
If I keep being in doubt, then yes, the correct thing would be to refill to full, and reset everything, and start from there I guess.

By the way, in general, does anyone know what determines if the SERVICE light will come up on the dash at all? As seemingly if an intermittent "no diesel additive left" is not enough for it to become ON.
