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.

Distance to a marque dealer from Barnstaple is the single biggest variable in what this ends up costing, and it is worth settling before anything is towed. Operators around Barnstaple tend to run vehicles hard and top up from bulk, which puts fluid quality rather than driver error at the top of the likely-cause list. 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. Cold mornings in Devon 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.
