SCR technology with AdBlue is becoming increasingly commonplace, but isn’t yet fitted to every diesel car. The more recently your car was built, the more likely it is that it’ll use AdBlue to reduce its emissions. If you’re driving a new model launched since 2016, it’s highly likely it’ll use AdBlue; if you’ve bought a new car since 2016 which was on sale before that date, it’s possible it won’t require it.
Many people are unaware the system is installed until a warning message appears on the dashboard announcing the AdBlue tank needs replenishing. As the SCR system has no effect at all on how the car drives, it’s not always obvious whether a car is so-equipped.
If you’re in doubt as to the presence of an SCR system that requires AdBlue, the owner’s handbook for your car will help. You can check it for the location of the AdBlue filler cap – if one isn’t listed, it can be assumed that SCR was never fitted to your model of car, although a call to your local dealer is still recommended.
If it does provide a location for the AdBlue filler, check that location on your car for its presence. Where fitted, it’s commonly beside the fuel filler, but some cars have it concealed by the boot carpet, either on the floor or at either side.
