AdBlue in diesel in Watford — what is different locally
Vehicles in Watford are often found on the hard standing of a yard or a forecourt, and an on-site drain avoids a recovery movement that would otherwise cost more than the repair.
Getting to a dealer from Watford usually means a recovery movement, so the sequence matters: drain and flush first, establish whether the system has latched, and only then decide whether a dealer visit is unavoidable. Vans and pickups around Watford carry larger AdBlue tanks, are refuelled by whoever is on shift, and lose a working day rather than an evening when they are off the road.
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. AdBlue freezes at around −11 °C, and Hertfordshire gets there most winters. Frozen fluid is not spoiled fluid — the tank and lines are heated by design and it thaws on its own — but a genuine level or quality fault reads much the same on the dash, which is why the two get confused.
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. Coverage runs across Hertfordshire on the same basis, with volume and disposal priced in before anyone sets off.

No. This is the opposite failure. Nothing has entered the exhaust or the SCR circuit — the AdBlue is in the fuel side, where it does not belong. Your SCR system is untouched.
