Can you overfill an AdBlue tank on an Audi?
Can you overfill AdBlue? Overfilling the AdBlue tank can be dangerous for your vehicle. This is because AdBlue is a urea-based solution, which means it is corrosive and can damage your vehicle’s components if spilled. Some common fault codes related to AdBlue include P20EE, P205C, and P20B9. P20EE indicates a malfunction in the AdBlue system, specifically a low exhaust gas sensor; P205C indicates an AdBlue fluid quality issue; and P20B9 indicates a low AdBlue line pressure.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.
