AdBlue does not mix with diesel. It is water-based and diesel is not, so the two separate — and because AdBlue is denser, it settles to the bottom of the tank. This matters more than it sounds. Because there is no mixing, there is no dilution, and because there is no dilution the "small amount" reasoning that works for petrol in diesel does not apply here at all. Densities: AdBlue around 1.09 kg per litre, diesel around 0.83. The heavier liquid goes to the bottom. The fuel pickup is at the bottom.

Dealer coverage across West Yorkshire is thinner than the map suggests once you need a specific marque, and a wasted recovery to the wrong workshop is an expensive way to find that out. Light commercial density around Castleford means a fair share of calls are fleet vehicles where the driver and the owner are different people, and the decision has to be made by someone not standing at the vehicle. The cost split is simple and it is stated up front: the call-out, the drain and flush, and separately anything the SCR system itself needs. Cold mornings in West Yorkshire produce a run of calls that turn out to be nothing more than fluid below −11 °C in a tank that has not yet warmed, and telling that apart from a real fault saves a wasted visit. Local conditions shape how this is done, not whether it can be. That is a question about the fluid and the tank. Normally put right by a drain and flush, provided the engine has not been run.
