P0410 indicates a general malfunction in the secondary air injection system. This system pumps fresh air into the exhaust during cold starts to help the catalytic converter reach operating temperature faster and reduce cold-start emissions. The code covers pump, valve, and circuit faults.

The secondary air pump on the 2.0 FSI and EA888 engines is located in the front of the engine bay and is very susceptible to moisture damage. The combination valve (N112) frequently sticks shut with carbon. VW issued a technical service bulletin for pump failures on early Mk5 models.

The N52 and N55 engines use an electric secondary air pump that commonly fails after 80,000-120,000 km. BMW pump failures are often caused by moisture entering through deteriorated check valves. The pump is located behind the front bumper on many models, making it exposed to road spray.

The 2.0 TFSI in the B7 and B8 A4 shares the VW secondary air system. The combination valve is the most common failure point. Audi recommends replacing the valve and pump together if the pump shows signs of moisture damage.

The 3.6 V6 and 4.8 V8 in early Cayenne models have two secondary air pumps (one per bank). Both pumps and their check valves are prone to failure. Repair costs are higher due to dual-bank design. The pumps are accessible from underneath the vehicle.

Ces codes apparaissent souvent avec P0410 ou indiquent des problemes connexes :
It is an emissions system that pumps outside air into the exhaust manifold during cold starts. This extra oxygen helps burn off unburned hydrocarbons and brings the catalytic converter up to operating temperature faster, reducing cold-start pollution.
The vehicle will drive normally, but the check engine light will stay on, preventing you from passing an emissions test. In the EU, this will cause a failure at your periodic vehicle inspection. It is best to repair it before your next test.
Moisture can enter the air pump through a faulty check valve or through condensation in the hoses. In freezing temperatures, this water turns to ice inside the pump, which can seize and burn out the motor when it tries to run on the next cold start.
No. Many modern engines achieve fast catalytic converter light-off through engine management strategies without a dedicated air pump. The system is more common on European vehicles, particularly VW/Audi, BMW, and Porsche models.
Ensure the check valve between the pump and exhaust is functioning properly to prevent moisture backflow. Some owners in cold climates install an inline filter or drain. Regular short trips in cold weather are the main cause of moisture buildup.
