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

The honest comparison is the total: call-out, work, any parts, and the time the vehicle is standing. All four are discussed before travel. Winter around Chelmsford brings the freezing question up constantly: the fluid freezes near −11 °C, the system is designed for it, and the dashboard message is the only thing that needs interpreting.
