Because Cosham Portsmouth 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 Portsmouth sees sustained cold, the first thing to establish on a level warning in January is whether the fluid has simply not thawed yet. Whether this job is a roadside one depends on the direction of contamination rather than on the postcode. Normally put right by a drain and flush, provided the engine has not been run.
