This used Audi 4L0131911B Diesel Exhaust Fluid (DEF) supply line, also known as a DEF hose, is a genuine OEM part removed from a salvage vehicle. It supersedes 4L0131911A and 4L0131912, and fits Audi Q7 models with the 3.0L V6 diesel turbocharged engine (2967cc). This DEF hose routes fluid from the tank to the injection system; a clog or leak can trigger a warning light or reduced engine power.
