DS5 (2017) Urea/Engine/Service Lights

Post by bamo »

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?

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:

There are lots of issues with these across multiple manufacturers.
