Can you drive with an AdBlue warning light?
So, how long can you drive after the AdBlue warning? The answer depends on the make and model of your vehicle. Generally speaking, you should be able to drive for around 500-2000 miles after the warning light comes on. If your AdBlue level is low, a notification will appear in your vehicle’s information cluster display, and a warning light will illuminate on your dashboard. Be advised that your diesel engine is not permitted to operate without AdBlue.Most vehicles which require adblue will give you a warning when there’s about 2-3 litres left. Depending on the vehicle and how you drive it, this will give you about 1,200 to 1,500 mile range.AdBlue Off refers to the process of deactivating the AdBlue system in a vehicle. This can be achieved through software modifications, such as ECU remapping, or by physically removing the system’s components from the engine.If you run out of AdBlue, your diesel vehicle will not be able to start or continue driving for long. AdBlue is a fluid used in diesel engines to reduce harmful emissions – so, if the AdBlue tank runs dry, the system detects this and triggers a warning on your dashboard.

You should never allow your car to run out of AdBlue. If it does, the engine will go into ‘limp’ mode, drastically reducing power to keep NOx emissions within legal limits. A warning will appear on the driver’s display, and you should refill the AdBlue tank as soon as possible. If you run out of AdBlue™, your vehicle will not re-start after you turn off the engine – this is a condition of the EU6 emissions legislation and applies to all types of vehicles.

Keep filling the tank with AdBlue until the warning light goes off. Ignite the engine and keep it running for a few minutes to detect the new level of AdBlue.
