How To Reset Adblue Warning VW Crafter?

You’re driving your new VW Crafter and you notice a warning light on the dashboard with the word ‘Adblue’ flashing. What does this mean? Have you broken it already? Is it something serious? There are so many questions in your mind and you don’t know where to start searching for answers.

This article explains everything about the AdBlue system in detail and how to reset AdBlue warning light on VW Crafter.

What is AdBlue and what does it do?

AdBlue is a fluid used in the Diesel Exhaust Fluid system (DEF). When Diesel is burned in an engine, harmful carbon dioxide and nitrogen oxide gases are created. The DEF system captures these harmful gases before they are emitted into the atmosphere by the exhaust.

The DEF is stored in a tank and then added to the fuel tank when trucks pass a fueling station ‘on the fly’. The DEF is then mixed with the fuel and burned in the engine to convert harmful gases into harmless CO2 and water. This process is called ‘SCR’ which stands for ‘Selective Catalytic Reduction’.

Why did my VW Crafter’s AdBlue light start flashing?

There are many reasons why the AdBlue warning light on your Crafter starts flashing. The most common reason is that the AdBlue level is low and needs to be refilled. If the AdBlue level is very low, the light may start flashing when you start the engine. The light may also flash if the fuel tank isn’t empty. The light will flash to remind you to refuel the tank. If none of those reasons apply to your Crafter, then you might have a serious problem. You should stop driving the truck immediately and take it to the repair shop. You might want to call your insurance company as well.
