VAG Error Code: 16795
EOBD II Error Code: P0411

Fault Location:
Secondary Air Injection (AIR) System - Incorrect Flow Detected - Intermittent

Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.

Wiring/Connector(s).
Fuel Pump Relay (J17) faulty.
Hoses/Pipes to/between Components faulty/clogged.
Secondary Air (AIR) Injection Pump (V101) faulty.
Secondary Air (AIR) Injection Pump Relay (J299) faulty.
Secondary Air (AIR) Injection Solenoid Valve (N112) faulty.

Possible Solutions:
Check/Replace all faulty Wiring/Connector(s).
Check Fuel Pump Relay (J17).
Check Hoses/Pipes to/between Components.
Check Secondary Air (AIR) Injection Hoses/Pipes for Carbonization.
Check Secondary Air (AIR) Injection Pump (V101).
Check Secondary Air (AIR) Injection Pump Relay (J299).
Check Secondary Air (AIR) Injection Solenoid Valve (N112).

When is the code detected?:
The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system.

Description:
An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump. The Powertrain Control Module (PCM) also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The Powertrain Control Module (PCM) enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.
