A used Audi EGR combi valve pipe / line, OEM part number 078131831B, is a genuine factory component removed from a donor vehicle. This exhaust gas recirculation pipe connects the EGR valve to the intake system. A cracked or clogged EGR line can trigger a check engine light and cause rough idle or reduced fuel economy. It fits 2.8L and 4.2L V6 and V8 engines from Audi and Volkswagen applications.
