Technical Analysis

REF: #3518C6

The combination of P2015, P2008, and P2016 indicates swirl flap linkage wear and actuator position drift on VAG 2.7/3.0 TDI V6 engines (EA896/EA897).

Expected Symptoms

Glow plug light flashing and DPF icon illuminated on instrument cluster on AUDI (DTCs: P2015, P2008, P2016)
Engine enters limp home mode restricting engine output above 2,200 RPM
Acrid exhaust odor and elevated fuel consumption due to aborted DPF regenerations

System Impact

Drivetrain
Engine Control
Emission Control

Potential Fault Sources

01Defective differential pressure sensor G450 or split silicone sample lines (affecting AUDI subsystem for P2015, P2008, P2016)
02Severe soot loading in DPF caused by short-trip driving and fouled injectors
03Sticking EGR cooler changeover flap or faulty exhaust gas temp sensor G235 (logged fault: P2015)

Workflow / Methodology

01

Verify supply voltage and sensor telemetry for P2015, P2008, P2016 on AUDI with multimeter at key ON.

02

Check DPF differential pressure with key ON: must read precisely 0 hPa (0.48–0.52 V).

03

Query calculated soot mass and oil ash volume in ECM live data blocks.

04

Execute service regeneration cycle under load following sensor replacement.

Vanliga frågor om dessa felkoder

Vad är den primära orsaken till felkoderna?

The combination of P2015, P2008, and P2016 indicates swirl flap linkage wear and actuator position drift on VAG 2.7/3.0 TDI V6 engines (EA896/EA897).

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?

Install an upgraded reinforced linkage repair kit with brass/aluminum sockets, or replace manifold assemblies and motors. Clear DTCs.
