Why is my AdBlue light still on after filling it up?
When the AdBlue light remains on after refilling, the system may need a reset via the vehicle’s onboard diagnostics. Check the AdBlue tank sensor for faults or contamination. Ensure the correct AdBlue fluid was used and the tank cap is properly sealed. The findings suggest that inconsistent Adblue composition may reduce emissions reduction effectiveness and potential engine performance issues. Based on the available research, it is generally recommended to avoid mixing Adblue brands to ensure optimal performance and emissions compliance.It makes no difference which AdBlue® you use in the automobile industry. AdBlue®is the name of the product however customers can purchase different branded AdBlue® provided the manufacturer produced the AdBlue® following ISO 22241 standards.Yes, AdBlue and DEF are chemically identical. Both consist of a 32. SCR systems.One of the most frequent issues with AdBlue is crystallization. When exposed to air or not properly managed, AdBlue can crystallize, leading to clogged injectors and filters. This blockage can cause the system to malfunction, leading to increased emissions and potential engine damage.
Why is the AdBlue warning light on but the tank is full?
AdBlue pump issue: The AdBlue pump may be malfunctioning, causing the system to not be able to pump AdBlue into the exhaust system. AdBlue system error: There could be an error in the AdBlue system itself, causing it to not recognize that the tank has been filled. Never overfill the system, either.

As AdBlue is not compatible with any engine materials it can very quickly corrode all components and pipework within the engine. If this happens the entire fuel system will need to be replaced. You must contact a professional to drain the tank immediately and dispose of all contaminated fluid.The next step is to empty the Adblue tank completely. Use the funnel and container to catch the fluid and make sure to dispose of the Adblue properly, as it can be harmful to the environment. After that, use the Adblue removal solution recommended by the vehicle manufacturer to flush the Adblue system components.AdBlue injector issue: The AdBlue injector may be clogged or damaged, causing the system to not be able to properly inject AdBlue into the exhaust system.
