What happens if your car runs out of AdBlue? If you run out of AdBlue while you’re driving, then the engine’s power and performance will be reduced to ‘limp home’ mode to limit its emissions and once the engine has stopped, it won’t re-start until the AdBlue tank is refilled.
What is an AdBlue fault?
AdBlue also known as Diesel Exhaust Fluid (DEF) is a urea and water based solution that is injected into the car’s exhaust system before harmful nitrogen oxide comes out of the tail pipe. Whenever this warning pops up, it means there is something bad with NOx sensor.
What happens when Mercedes AdBlue runs out of Def?

When to add fluid to AdBlue DEF tank?
The reserve level in that AdBlue/DEF tank once you hit that light is around 2000-2500 miles. One DIY recommendation is to add 5 gallons from bulk 2.5 gallon bottles at/over 10K miles before you get that low/reserve light – the light otherwide will normally happen somewhere around 13.5K-14.5K miles.
