This used OEM right-side EGR Combi Valve Adapter (079133864B) was removed from a salvage Audi. Also called the EGR combi valve adapter, it connects the exhaust gas recirculation system on 4.2L V8 engines (4163cc and 4172cc). A failing adapter can cause EGR flow errors, rough idle, or a check-engine light.
