AdBlue Technology

AdBlue systems are being fitted to some of our latest diesel cars.The technology is designed to reduce harmful exhaust emissions through adding AdBlue fluid into the exhaust system, so this fluid may need refilling from time to time.

Has my car got AdBlue?

Your car has got AdBlue if it has an extra, smaller filler cap, marked ‘AdBlue’, next to the diesel filler where you usually top up the fuel.

What you need to know.

Your car has an advanced system that will alert you if the AdBlue is running low and requires a top up. W R Davies will, as part of your vehicles standard service, check and refill the AdBlue at no cost to you. If you haven’t had the car for very long or covered many miles, chances are you will not need to take any action in between services, however, if you cover more miles, you may find that you need to refill the AdBlue tank.

If the warning light appears (please do not ignore it your car will not start if the tank runs completely dry). You now have two options:​

You can top up the tank yourself, using AdBlue fluid which is widely available to purchase at petrol stations and motoring stores.The cost of this will be your responsibility.

You can get in touch with W R Davies Nissan and we will top up the AdBlue and there will be no charge to you. (You may also visit any Motability Scheme dealer who will help you).

Why AdBlue is used?

To help reduce harmful pollutants, European emission standards set limits for the level of exhaust emissions produced by vehicles. The new Euro 6 Regulations apply to all new registrations from 1st September 2015, when all new cars had to meet the latest emissions requirements.

AdBlue is an effective way of bringing diesel engines up to the standard required to meet Euro 6 Regulations.

How it works

  • Cars with the latest technology are able to inject the AdBlue liquid into the exhaust gasses of diesel powered engines.
  • AdBlue is a clear liquid made up of demineralized water and urea.
  • The liquid combines with harmful emissions normally produced in the exhaust, such as nitrous oxides, breaking them down into environmentally friendly gases like nitrogen and oxygen.
  • This is known as ‘selective catalytic reduction’ or SCR technology.

Tips & Recommendations

  • Don’t store a spare bottle of AdBlue in the boot or garage, as spillages can be harmful and the liquid itself can get contaminated or degrade over time.
  • Avoid contact and wash your hands after use as it can irritate your skin and eyes.
  • Make sure the liquid doesn’t touch the car’s paintwork as it can be corrosive.
  • The amount of AdBlue needed varies depending on the vehicle and driving behaviour, for more advice consult your vehicles handbook or contact W R Davies Nissan Service Department in Telford or Stafford.
