P2015 means the position feedback of the intake manifold runner or swirl flaps on bank 1 is electrically present but implausible. How it is judged depends on the design. Diesels with a smart swirl actuator send position as a pulse-width signal: GM's 2018 diesels fail a pulse period below 0 or above 64 ms in 52 of 62 samples (Type B), and on the Opel/GM 2.0 CDTi in the Saab 9-5 (2010) the ECM flags a wrong frequency from the actuator, with sub-codes for period and high and low time (Type A). Ford's petrol engines call it position sensor over travel. Audi and Volkswagen use it widely on 2.0 TFSI: a corroded flap valve N316, a flap that separated inside the manifold, and on the 4.2 FSI a deformed seal behind the flap potentiometer that made the linkage stick. After a manifold or valve replacement the flap adaptation has to be run, or the code returns.

Likely causes

Flap linkage sticking or flap separated inside the manifold
Corroded or faulty flap control valve
Actuator electronics or position sensor faulty
Flap adaptation not performed after repair

Symptoms

  • Malfunction indicator lamp on
  • Rough idle or weaker low-speed torque
