DS5 (2017) Urea/Engine/Service Lights
Just had these alerts pop up. Garage says P20E8 error found, they checked & reset everything but 2miles later they are back. Wondered if any othe DS5 owners had similar issue?

Re: DS5 (2017) Urea/Engine/Service Lights
This code relates to the reductant pressure being too low.
This can mean there is a leak in the Urea system somewhere - either the reservoir or the supply line somewhere. It does need looking at earlier rather than later as at some point if there is a leak and it becomes worse, then the time remaining before you cannot start the engine will decrease rapidly.

Yes - still under warranty - so take advantage of it. I've seen some pretty awful failures of these -
This is what can happen when there is a leak at the Adblue supply line to the injector - the Adblue dries and crystalises:
