P11AE/004526 - Cam Adjustment Actuator A; Cylinder 4: Implausible Signal​

Possible Symptoms

  • Possible loss of power, due to AVS (Audi Valve Lift System) default position affecting lower (1000~3100 RPM) torque curve
  • All non affected actuators are switched to the Large Valve Lift position.
  • Fault code entry without EPC or Check Engine lights due to no deterioration of Exhaust Emissions

Possible Causes

  • Wiring and/or connections (short circuit?)
  • Voltage supply failure to the Cam Adjustment Actuators
  • Faulty Engine Control Module
  • Worn or damaged Camshaft/Cam Element(s)

Possible Solutions

  • Check wiring and connections
  • Check for battery voltage at Cam Adjustment Actuators
  • Check Engine Control Module with [Output tests]
  • Repair/Replace worn or damaged Camshaft/Cam Element(s)

Special Notes

  • See the Ross-Tech forum post: - Case Study: P11A7 00 - Audi Valve Lift System - E888 engines
    • This Fault code is for the F372-Control element (7) for camshaft adjustment, Cylinder [4]
    • AVS system function when coolant temperature is above 14°F (–10°C).
    • Maximum of 3.0 amperes for each Cam Adjustment Actuator
