As an automotive expert with a focus on modern emission control systems, I can provide you with a detailed explanation of what happens when you run out of AdBlue.
AdBlue is a non-toxic, non-flammable, and environmentally friendly urea solution that is used in vehicles equipped with Selective Catalytic Reduction (SCR) technology. This technology is designed to reduce harmful nitrogen oxide (NOx) emissions from diesel engines, making them more environmentally friendly. AdBlue works by injecting the urea solution into the exhaust stream, where it breaks down into ammonia and other compounds. The ammonia then reacts with the NOx gases in the presence of a catalyst, converting them into nitrogen and water, which are harmless and can be released into the atmosphere.
When you run out of AdBlue, several things can happen depending on the specific vehicle and its design. Here are the general steps and consequences:
1. Warning Indicators: Most vehicles will have a warning light on the dashboard that alerts the driver when the AdBlue level is low. This is the first indication that you need to refill the AdBlue tank.
2. Performance Reduction: Once the AdBlue tank is empty, the SCR system will not be able to function properly. As a result, the vehicle will enter a "limp mode" to comply with legal emission standards. This is done by reducing the engine's power output to ensure that the NOx emissions remain within the legal limits.
3. Emission Compliance: Even with the reduced power, the vehicle will still operate within the legal emission limits. This is because the engine control module (ECM) adjusts the engine's operation to ensure compliance with environmental regulations.
4. Temporary Operation: Some vehicles may allow you to drive for a limited time or distance after the AdBlue tank is empty. This is to ensure that you can reach a service station to refill the AdBlue.
5. Refilling: It is essential to refill the AdBlue tank as soon as possible to restore the vehicle's full performance and SCR system functionality.
6. Long-Term Effects: If AdBlue is not refilled and the vehicle continues to be driven, it could lead to more severe consequences. The ECM may further limit the engine's performance, and in some cases, the engine may shut down to prevent damage to the catalytic converter or other components.
7.
Engine Protection: Contrary to some beliefs, running out of AdBlue will not damage the engine itself. The engine is designed to operate safely even in the absence of AdBlue. However, it is crucial to refill the AdBlue to avoid potential damage to the SCR system and to maintain legal emission compliance.
8.
Service and Maintenance: Regular maintenance and timely refilling of AdBlue are essential to keep the SCR system in good working order. Failure to do so can lead to increased emissions and potential legal penalties.
In conclusion, while running out of AdBlue does not damage the engine, it does affect the vehicle's performance and emission compliance. It is crucial to monitor the AdBlue level and refill the tank promptly to ensure optimal vehicle operation and environmental responsibility.

No, the engine will not be damaged when you run out of AdBlue. ... If your engine is equipped with SCR technology, your vehicle will lose power, and reduce its emission according to legal standards. The vehicle's performance will be restored when AdBlue levels are up again.
