Audi EGR Valve Vacuum Pipe / Line, OEM 078131492C, is a used genuine part removed from a donor vehicle. This right-side vacuum line (also replaces 078131492A) routes vacuum to the EGR valve on the 2.7L 2671CC V6 DOHC Turbo engine found in the A6 Quattro, Allroad Quattro, and S4. When the pipe cracks or leaks, it can cause EGR malfunctions, rough idle, or a check-engine light.
