What does the AdBlue® warning on my diesel vehicle show?
The Euro VI European standard requires any vehicle with an AdBlue® tank to have an audible and visual warning system as part of the car’s software. The warning system increases in intensity as the tank empties. The first warning appears when there are around 1440 miles (2400 km) left before the tank is completely empty. If the AdBlue® tank is empty, or if the AdBlue® system is faulty, it will not be possible to restart the vehicle.
How does the lack of AdBlue® additive warning work?
An indicator on the dashboard will inform you of the remaining AdBlue® range, either when you start the car or intermittently while driving. Some manufacturers do not provide information before the vehicle’s remaining range reaches around 1440 miles (2400 km). Then, depending on the vehicle, you will be alerted periodically at around 900 miles (1500 km) and then 360 miles (600 km). The warning system cannot be disabled before the reagent tank has been refilled.
When you are nearing breakdown, your speed will be restricted or the number of possible start-ups remaining will be indicated. A message will be displayed permanently on the dashboard to inform you of the conditions needed to return the AdBlue® system to full operation.
Does the AdBlue® warning not disappear when you have just refilled the tank?
If you fill up when your AdBlue® tank is empty, you will need to put in a minimum amount so that the AdBlue® poured in is detected by your car’s electronic system. You must then wait a few minutes before switching on the ignition and wait 10 seconds before turning on the engine.
