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).

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.
