Technical Analysis

REF: #3CBB16

The combination of P2015, P2004, and P2006 indicates intake runner flap over-rotation due to a worn mechanical plastic stop on VAG 2.0 TSI and TDI engines.

Expected Symptoms

Check engine light illuminated with sudden boost drop under hard acceleration on VOLKSWAGEN (DTCs: P2015, P2004, P2006)

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 VOLKSWAGEN subsystem for P2015, P2004, P2006)

02Boost control solenoid N75 leakage or split charge air hose

03Ruptured diaphragm in PCV oil separator assembly (logged fault: P2015)

Workflow / Methodology

Verify supply voltage and sensor telemetry for P2015, P2004, P2006 on VOLKSWAGEN with multimeter at key ON.

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

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

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 P2015, P2004, and P2006 indicates intake runner flap over-rotation due to a worn mechanical plastic stop on VAG 2.0 TSI and TDI engines.

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?
