This Audi intake camshaft (OEM 078109021Q) is a used genuine unit for the left bank. It also replaces 078109101BT. Designed for the 2.7L 2671CC V6 DOHC turbo engine—found in the A6 Quattro, Allroad Quattro, and S4—this cam controls valve timing on the intake side. A failing cam can cause rough idle, misfire, or reduced power.
