What is the Most Common Problem with AdBlue?

Model: (Various brands) Various
Part: AdBlue warning light

What is the most common problem with AdBlue? It is definitely crystallisation, which arises from poor quality Urea. Unfortunately, we know the issues with sourcing Urea, which used to come 90% from Ukraine, and now comes from third-party producers that often do not provide high-quality products. The only tool users have to avoid problems related to poor quality is to add an additive. There are excellent ones available on all e-commerce sites, such as Tunap 988, which can be found on Amazon for £20.95, or Bardahl anti-crystallisation additive, available on eBay for £31.28.
