From what I'm hearing on the subject, this is looking rather serious.Urea being used as an agricultural input as fertilizer plus along with demineralised water it's used as diesel exhaust fluid
As a problem, it could be summed up as saying it's rather like someone exactly two years ago noting that a strange virus has been reported in China but assuming "it's probably nothing". It's a great big elephant standing there that it seems few are paying attention to thus far despite the danger it poses.
The seemingly easy workaround of just not having the emissions controls working isn't anywhere near as simple as it might seem. First because of the legal implications. No reputable business that owns trucks, or a mechanic, is going to do it without government passing appropriate legislation that makes it legal. Then there's the logistics of actually doing it - there's rather a lot of trucks, buses and so on around.
Trying to simply fool the system by simply putting demineralised water in, instead of AdBlue, doesn't work either - once the sensors detect excess NOx it cripples the engine's performance basically.
So it seems that having rather a lot of trucks off the road is indeed a very plausible problem that's going to happen in 2022.
I'm not a truck expert but that's my understanding of the situation as at present. It's looking rather serious.
