Most Reported On
P11AA is an OBD-II diagnostic trouble code meaning “Camshaft Adjustment Actuator 'A', Cylinder 3 - Implausible Signal.” This is a VAG (Volkswagen/Audi) manufacturer-specific code (Ross-Tech P11AA/004522) indicating an implausible signal from camshaft adjustment actuator 'A' on cylinder 3, part of the Audi Valve Lift System (AVS) that switches between intake cam lobe profiles. When detected, the affected actuator defaults to its standby position and unaffected actuators switch to the large valve-lift position, which can cause a loss of power in the lower (roughly 1000-3100 RPM) torque range. The fault is often logged without an EPC or Check Engine light because exhaust emissions are not degraded. This code is most commonly reported on 2011-2022 Volkswagen Touareg, with repair costs ranging from $250 to $1,500.
