Recurring Fault, AdBlue Warning Despite Full Urea Tank

Model: Peugeot 3008 MK 2, P84 - Years 2016-2023
Part: AdBlue warning light

While not sharing the opinion of the understandably frustrated user, who is likely fed up with the recurring warning of a faulty AdBlue system in their Peugeot 3008 - despite having a full urea tank - the fault mode, which likely starts from the feed pump, can also be caused by poor quality fluid. Unfortunately, AdBlue is urea-based, a natural product that used to come 90% from Ukraine, whose current situation we all know. Therefore, the product currently available may not be of high quality, which certainly affects the operation of the sensors that were calibrated for a specific type of product that may no longer exist. This is not a consolation for those in trouble like our YouTuber, but it may help to understand.
