The nearest franchised dealer able to run a manufacturer forced reset can be a significant distance from Farnham, which is exactly why a latched inducement is worth diagnosing on site before the vehicle is moved anywhere.

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. Location changes the logistics of this job and nothing else about it — the severity is set by what went into which tank. Frequently needs SCR component work rather than a drain.
