    Technical Analysis

    REF: #6FD40F

    The combination of P2009, P2010, and P2015 indicates an electrical short circuit inside the intake runner flap actuator motor V157 on Audi 2.0 TDI engines, often caused by oil fouling the internal PCB.

    Expected Symptoms

    Check engine light illuminated with sudden boost drop under hard acceleration on AUDI (DTCs: P2009, P2010, P2015)
    Rough idle and sluggish throttle pickup from a dead stop
    Misfiring and hesitation during high-speed highway overtaking (2,500–3,500 RPM)

    System Impact

    Drivetrain
    Engine Control
    Emission Control

    Potential Fault Sources

    01Sticking electronic wastegate actuator or heavy carbon buildup on intake valves (affecting AUDI subsystem for P2009, P2010, P2015)
    02Boost control solenoid N75 leakage or split charge air hose
    03Ruptured diaphragm in PCV oil separator assembly (logged fault: P2009)

    Workflow / Methodology

    01

    Verify supply voltage and sensor telemetry for P2009, P2010, P2015 on AUDI with multimeter at key ON.

    02

    Measure wastegate position feedback voltage at key ON: normal 3.5–3.9 V in closed position.

    03

    Smoke-test induction system and boost plumbing at 1.2 bar to pinpoint leaks.

    04

    Check crankcase depression with digital manometer at warm idle (-100 to -150 mbar).

    Assessment & Action Proposal

    Technical Recommendation

    Replace the faulty intake flap actuator V157, replace blown fuse, clean intake tract of oil and carbon, and clear DTCs.

    Vanliga frågor om dessa felkoder

    Vad är den primära orsaken till felkoderna?

    The combination of P2009, P2010, and P2015 indicates an electrical short circuit inside the intake runner flap actuator motor V157 on Audi 2.0 TDI engines, often caused by oil fouling the internal PCB.

    Kan man köra vidare med tänd motorlampa / varningslampa?

    Körning med aktiva felkoder kan leda till strypt motoreffekt (nödläge / Limp Home), blockerad partikelfilterregenerering eller följdskador på mekaniska komponenter. Felsökning bör genomföras omgående.

    Hur åtgärdas kombinationen på säkrast sätt?

    Replace the faulty intake flap actuator V157, replace blown fuse, clean intake tract of oil and carbon, and clear DTCs.
