Adblue removal refers to the process of disabling or bypassing the selective catalytic reduction (SCR) system in diesel vehicles that use AdBlue, a urea-based solution, to reduce emissions. This modification is typically sought by vehicle owners looking to enhance engine performance or avoid the costs associated with AdBlue refills. While Adblue removal may offer short-term benefits, it's essential to consider the environmental impact and legal implications, as it can lead to increased emissions and violate regulations designed to curb pollution.
