The Audi EGR Adapter Pipe / Line (OEM 079131166D) is a used genuine part from a donor vehicle. This left-side EGR line routes exhaust gas back into the intake on 4.2L V8 engines found in the Audi R8 and RS4. When the adapter pipe clogs or develops a leak, common symptoms include rough idle, reduced performance, and a check-engine light for EGR flow issues. Also known simply as an EGR line, it’s a direct factory replacement for restoring proper emissions recirculation.
