The Diesel Exhaust Fluid Tank, also known as the DEF Reservoir, is a critical component in the emissions control system, particularly for Audi Q7 models from 2010 to 2012. Located near the rear of the vehicle, this tank stores the diesel exhaust fluid necessary for the selective catalytic reduction process, helping to reduce nitrogen oxide emissions. Common issues that necessitate replacement include leaks, clogs, or damage due to impact. OEM part number 4L0131878D, along with compatible numbers such as 4L0131878C and 4L0131880B, ensure proper fitment. This part is ideal for Audi Q7 3.0L V6 Diesel and Gas engines. Integrating this authentic OEM part restores optimal performance and compliance with emissions standards.
