Specialist SCR workshops in Surrey are scattered, and the nearest one to Walton-on-Thames may not be the nearest one that can actually clear this particular fault. Vans and pickups around Walton-on-Thames 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. Where a vehicle is on contract or on a job, the cheapest outcome is almost always the one that avoids a recovery movement, even if the roadside work costs more per hour. Cold mornings in Surrey 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. Whether this job is a roadside one depends on the direction of contamination rather than on the postcode. Frequently needs SCR component work rather than a drain. Quoted before a technician travels.
