How can I clear error messages in my 2013 Renault Latitude without going to a dealer?

A lot of owners of cars such as Peugeot, Mercedes-Benz, BMW, Renault and even Porsche tend to steer away from the higher costs of dealership servicing once the vehicle is out of warranty. That has led to the establishment of a raft of specialists in particular brands who are not factory dealerships. So, the trick is to find such a specialist independent workshop and take the car there.

Such a workshop should have all the test gear and service equipment, not to mention model-specific know-how, to tackle any job (including this one) without the hourly rate of a factory dealership with its higher overheads.
