Welcome to the forum. Attachment 2748
VAG Error Code: 16795 EOBD II Error Code: P0411 Fault Location: Secondary Air Injection (AIR) System - Incorrect Flow Detected Possible Cause: Malfunction Indicator Lamp (MIL)(K83) active. Engine hesitation. Wiring/Connector(s). Secondary air injection (AIR) pump leaking/blocked or stuck open/closed. Secondary air injection (AIR) valve (N112) leaking/blocked or stuck open/closed. Secondary air injection (AIR) hose(s). Faulty Vacuum hoses damaged. 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. As taken from my https://volkswagenforum.com/forum/ge...oftware-34973/ |
