A used OEM Audi EGR Adapter Pipe / Line, part number 079131166AQ, also replaces 079131166AN. This left-side exhaust gas recirculation component routes recirculated exhaust from the engine back into the intake system on 4.0L V8 turbocharged engines (3993cc). A failing EGR adapter pipe can cause exhaust leaks, reduced engine performance, or trigger a check engine light.
