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.

Because Cyncoed Cardiff sits inside a large urban dealer network, a vehicle that truly needs a dealer-level reset is not far from one — the question is whether it needs one at all. Traffic here is predominantly cars and light vans, so AdBlue tanks are small and are often only topped up when the warning appears — which is why a large share of local calls are fluid-quality and level-sensor faults rather than wrong fills. Downtime cost is usually what decides between a mobile fix and a recovery, and it is worth being blunt about it on the call rather than after the van arrives. Because Cardiff sees sustained cold, the first thing to establish on a level warning in January is whether the fluid has simply not thawed yet. 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.
