AdBlue service
It’s important that your vehicle doesn’t run low on diesel exhaust fluid (DEF), or even worse – run out.
A warning light would typically show on the dashboard when you’re running low, and your car or van will eventually go into “limp mode” to try to reduce the emission of harmful pollutants. Once they’ve run out of DEF, most modern diesel vehicles cannot be restarted, resulting in a premature and no doubt frustrating end to your journey.
AdBlue would normally be checked and replenished during a normal service, but it’s often necessary to top up between services.

You can refill AdBlue yourself by purchasing the solution and pouring it carefully into the appropriate tank (consult your owner’s manual, but it’s normally the tank with the small blue cap marked “AdBlue” or “DEF”). You can also find AdBlue pumps suitable for cars or vans at some road-side filling stations, usually near motorways or on routes used regularly by HGVs.
When refilling AdBlue yourself you must take great care not to spill the solution as it can corrode and otherwise damage car components, particularly those made of aluminium.
What is AdBlue?
While modern diesel particulate filters are able to capture much of the soot that older diesel engines would have exhausted, they require extremely high combustion temperatures in excess of 1800°C to do so. Unfortunately, these high temperatures result in an inadvertent increase in the volume of nitrogen oxides (NOx) generated, which are considered worse for the environment than the sooty particulate matter that DPF technology is designed to reduce.
Selective catalytic reduction works alongside the DPF to tackle these harmful NOx emissions, injecting DEF into the exhaust pipeline of any diesel vehicle that utilises SCR technology. DEF consists of urea and deionized water which the exhaust head converts to ammonia, which in turn reduces the NOx to non-polluting water and nitrogen, lowering the concentration of NOx in the diesel exhaust emitted from the vehicle.
“AdBlue” is one of a handful of brands of DEF and is a registered trademark of the German Association of the Automotive Industry (VDA). It’s generally associated with Volkswagen Group (VAG) brands, such as VW, Audi, SEAT and Skoda. Many other manufacturers use diesel exhaust fluid to reduce emissions and comply with Euro 6 regulations – Peugeot, Citroën, and DS Automobiles use “BlueHDI” branded SCR technology, while Mercedes-Benz’s use the marketing term “BlueTEC”.
