A used OEM Audi EGR Combi Valve, part number 079131101AJ (also supersedes 079131101AD). This right-side valve is from the 4.0L twin-turbo V8 (4.0 TFSI) found in the Audi A8, RS7, S6, S7, and S8. It regulates exhaust gas recirculation; a failing unit often triggers a check engine light and rough idle or hesitation under load.
