This used OEM EGR Combi Valve Adapter (part number 079133863B) is a genuine Audi component removed from a donor vehicle. It mounts on the left side of 4.2L V8 engines (4163cc and 4172cc) found in A6 Quattro, Allroad Quattro, and S4 models. This adapter connects the EGR combi valve to the exhaust system; when it fails or clogs, it can trigger a check engine light, rough idle, or reduced engine efficiency.
