From September 2015, the majority of new diesel cars will feature an AdBlue injection system. This allows for cleaner, more efficient cars, lower Nitrogen Oxide and CO2 emissions and better fuel economy.
Manufacturers have developed a treatment system called ‘Selective Catalyst Reduction’ (SCR), which converts nitric oxide into less harmful nitrogen and water. AdBlue is a non-toxic, non-flammable, odourless and biodegradable reducing agent that makes this conversion possible.
You may be required to top up your Adblue tank between services. You can refill the tank yourself when alerted by your Driver Informations System, or take your car to an Audi Authorised Repairer. Audi supplies AdBlue for £1.50 per litre, including VAT and labour. Contact your local Audi Centre or watch the video for more about AdBlue.
