AdBlue should only be used in diesel cars fitted with an SCR system, so if in doubt, consult the vehicle handbook.
As a rule of thumb, the more recently the diesel car was built,STARTER MOTOR the more likely it is to use AdBlue, as the Euro 6 regulations were introduced in 2015.
For example, SCR technology is fitted to all Land Rover diesel vehicles built from the 2016 model-year, while Jaguar, Audi, Citroen, Peugeot, Mercedes-Benz, SEAT, Skoda and Volkswagen all use AdBlue tech.
