Keep your secondary air injection system moving in one direction with the Standard Ignition Secondary Air Injection Pump Check Valve (AV62). It installs as a direct-fit replacement for the 2003-2006 BMW 325Ci and the 2003-2006 BMW 325i, restoring proper one-way airflow between the air pump and the exhaust.
A secondary air injection check valve is a one-way valve: during cold starts the system pushes fresh air toward the exhaust ports to help the catalyst reach operating temperature sooner, and this valve blocks that flow from reversing.
One-way flow control: Allows air from the secondary air pump toward the exhaust while preventing reverse flow back through the passage.
Protects the air pump: Helps keep hot exhaust gases and moisture from traveling back into the pump and plumbing.
Emissions system role: Works within the secondary air injection system that adds air to the exhaust stream during cold-start warm-up.
Signs this valve may need replacing include a check engine light with secondary air injection fault codes, or exhaust gases and moisture reaching the air pump. If a failed check valve is the cause, this replaces it; diagnose the system first, since these symptoms can have other causes.
Interchange: Manufacturer part number AV62.
Frequently Asked Questions
What does the AV62 check valve do?
It is a one-way valve in the secondary air injection system. It lets air from the air pump flow toward the exhaust and blocks that flow from reversing back toward the pump.
Which vehicles does this fit?
It is a direct-fit replacement for the 2003-2006 BMW 325Ci and the 2003-2006 BMW 325i. Check the Buyer's Guide tab to confirm the fit for your vehicle.
Why does a secondary air injection system need a check valve?
During cold starts the system pumps fresh air into the exhaust to help the catalyst warm up faster. The check valve keeps hot exhaust gases and moisture from flowing back into the air pump.
What are signs this check valve may need replacing?
A check engine light with secondary air injection fault codes, or exhaust gases and moisture reaching the air pump. Diagnose the system first, as these symptoms can have other causes.
Will replacing this valve clear my secondary air injection code?
If a failed check valve is the cause, replacing it addresses that fault. Confirm the diagnosis first, since the same codes can come from the pump, hoses, or other components.
