Standard Ignition CP631 vapor canister purge solenoid for the 2001-2005 Audi Allroad Quattro V6 2.7L and other vehicles opens and closes to release stored fuel vapor into the engine.
A failing purge solenoid can show up as a rough idle or a check engine light. Before you replace this solenoid, rule out a loose fuel cap, a split vapor hose or a wiring fault, since each can also set an evaporative emissions code.
It fits the 2001-2005 Audi Allroad Quattro V6 2.7L, the 2000-2004 Audi A6 Quattro V6 2.7L and the 2000-2002 Audi S4 V6 2.7L, and a single solenoid covers each of them. It meets OE specifications and is specially engineered for higher-mileage Audi applications.
