Technische Analyse

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).

Erwartete Symptome

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

Mögliche Fehlerursachen

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)

Vorgehensweise / Methodik

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

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

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

Execute service regeneration cycle under load following sensor replacement.
